A/N: First chapter of first actual fanfic. Feel free to criticize without restraint. The idea here is to create an episodic "5th season" of sorts, with more of a focus on continuity like Milo Murphy. I've always found some of the side effects of the lack of continuity a bit depressing, like the idea that all the main characters are by necessity not allowed to change in significant manners. It's why we only get angry Phineas in specials. There are going to be a couple of OCs, but the idea is to build them more as tools to serve stories then just "additions to the cast". I had a lot of fun writing this, so hopefully you all have fun reading it!

08/19/2020 A/N: An edit has been made to this chapter. In the previous version of the chapter, it was explained that the boys had discovered probability ions during "The Phineas and Ferb Effect". In this story, that is not the case, and I don't know if it was just because I was in the planning stage when I wrote this that I missed that detail. The edit is in the first block of the story, integrated as smoothly as I could hope to achieve. The two most important details are that they discovered the ions independently and that they never found anyone with negative ions.


Chapter 1: No Such Thing

Phineas Flynn and Ferb Fletcher were absolutely exhausted. The past school year had been a real drain on the brothers, limiting their creativity and free time. They had taken on so many ambitious clubs and projects that they hadn't even been able to get the gang together for a month or so. Phineas had excitedly rang up everyone the day before, the last day of school, to get them brainstorming for the traditional first project of the summer: The Rollercoaster. Ferb, though his blank expression and silent composure went unbroken, was also excited for the summer, though he had trouble sleeping with Phineas' hyperactivity. The alarm clock struck 7:59AM as Phineas sprung out of bed and slammed his hand onto the top with such force he smashed the whole thing to pieces.

"OUCH!" Phineas looked across the room at his startled older brother. "I guess I have a lot of pent up energy. Sorry Ferb." Ferb didn't reply. "OH! And -" Phineas looked down at the foot of his bed, where Perry had slept. He was already gone. "Huh. Ferb, have you seen Perry?"

Ferb didn't reply. Phineas sat in bed for a moment and then chuckled. "Of course you haven't! I just woke you up!" A slight grin crossed Ferb's face. The two threw off their covers and stood up on their beds. A set computer screens came down from the ceiling with the boy's potential clothing options on the display. Phineas chose his typical yellow and orange striped shirt and blue jeans. Ferb chose his typical white button up and purple slacks. The monitors quickly retreated into the ceiling compartment, and sets of robotic claws came down and took the clothes out of the closet, while another set quickly stripped the boys, arms raised, down to their underwear. The claws put the clothes on the boys, who had to hop a bit as the pants slid under their feet. Phineas excitedly jumped off of his bed and headed out the door, with Ferb following suit.

It was a perfect morning outside, and the sun had already been up since about 6 or 7. Linda and Candace were preparing scrambled eggs and french toast for breakfast. Candace was up uncharacteristically early. She had just yesterday gotten home from university, and her internal clock was off. "Good morning, Phineas!" she exclaimed as Phineas slid down the stair rail and into the kitchen. "Good morning, Ferb!" she repeated as Ferb walked down the stairs and took out some plates. Phineas grabbed the silverware and the two quickly set the table, replacing Lawrence's tea saucer and cup. Lawrence was reading the paper in his seat. Perry was sitting at the foot of Lawrence's chair.

"Thank you, boys. You excited to have another full summer?" Lawrence asked. Ferb gave him a thumbs up.

"Oh, that's where you were, Perry! Seems we were the last ones up, eh Ferb?" Phineas slid into his chair beside Ferb. "I told everyone to meet up in the backyard about 8:30, so we can stay in and eat for a while. Looks good, Mom!" Phineas turned to Candace, who was dishing out scrambled eggs from a hot pan. "And you look excited, Candace!" Candace finished rounding the table and put the pan in the sink as Linda slid a piece of french toast into each plate. The cooks finally sat down and Candace quickly tucked in.

"I-" her words were near-indiscernible through the food in her mouth "- need to get done here and head down-" she briefly choked on a piece of egg, and decided to swallow before continuing. Linda spoke up for her.

"She's heading to the Johnson's to help Jeremy pick out a venue for the wedding." Linda explained. Phineas nodded. A lot had happened in the three years since they started dating, but he and Ferb had basically known they were going to get married, as it was one of the few things Isabella let slip about their trip into future ("Wait! If you tell us any more, that could change the timeline!"). Phineas had pretended to be surprised and excited when he proposed a month ago. 19 was a bit young to be getting married in his opinion, but they'd been going out for such a long time it just seemed to make sense. Ha! He sounded like an adult. Linda had initially been a bit nervous about it, but she was now on board.

"Oh, that sounds nice. I was kinda hoping that you would be able to join us for the first project of the summer, but that's definitely more important." Phineas tapped the base of his fork against his chin, as if deep in thought. Candace raised an eyebrow in his direction.

"You're building another rollercoaster?"

"Yup."

"You kids and your imaginations. Do try to lay off them this summer, Candace, please?" Linda calmly began to clear her dishes as the boys finally started in. Phineas and Ferb had no idea what mom had meant by that. Candace always seemed sporting when it came to their outlandish activities.

"Sure thing, mom," Candace grumbled, "It's not like you'll see any of it this year anyways."

"I don't know, Candace," Lawrence intoned cheerfully, "Maybe you'll finally get 'em this year!" Lawrence grinned at Linda who could only sigh and half-chuckle.

Candace had thought the mysterious force surrounding the boys initially was a supernatural force that hid their activities from any adult, but there were a couple of holes in that theory as of recent. Her forensics studies had not helped her with her obsession, but Phineas and Ferb's discovery of probability ions while studying the performance of Danville High's football team had led her to believe that her struggle was indeed fruitless. It surely wasn't for lack of effort. The boys had discovered that things naturally go right for them. Any football game they attended or participated in (Phineas had a talent for it) went very well for Danville, and any they missed was a loss. Upon further study, the two discovered that the balance of the universe made them luckier than the average individual. They never, however, found anyone with the opposite condition that this implied. Linda left the room and Candace began to text on her phone.

Ferb tugged on Candace's shoulder from next to her. He cleared his throat and, after a brief pause, Phineas spoke up. "That reminds me, Candace! You know how Mom never sees the cool stuff we make?" Candace nodded along dispassionately. "Well, apparently that had something to do with our overwhelming amount of positive probability ions, right?" Candace nodded again. Phineas began to once again tap his fork against his chin. "It's the strangest thing; we were running some health diagnostics the other day and we found that our ionic concentration is decreasing. It's not hurting us or anything, so I'm not too worried, but while we might end up being less lucky, it does mean Mom might be able to see something we do now." Candace perked up.

"What do you mean, 'ionic concentration'? Does that mean I have a shot at busting you this time around?" Candace was intrigued.

"If that's how you want to put it. Although I do wonder where our ions are going, since the law of energy conservation implies that the energy they did have would have had to go somewhere..." Phineas continued to mumble to himself, as not to lose his train of thought. Candace, however, was very quickly losing hers.

I finally have a real chance of busting the boys? Why did this have to happen so late? I'm practically an adult! I have so many responsibilities to attend to, and Jeremy, and the wedding, and school, and... Jeremy. Candace wasn't sure if Jeremy would be able to put up with another summer of her neurotic compulsions, even though he usually enjoyed it. Deep in thought, she rested her elbow on the table and her head on her hand. She should head over to the Johnson's soon.

Phineas and Ferb had cleaned their dishes and pushed their chairs into the table, leaving Lawrence and Candace sitting at the table. Lawrence looked over at Candace, who was still debating her options. "If you would like me to drop you off, I'm heading to the shop in five. I'll be heading to the Picnic in the Park celebration later today. Grab the boys and head down when you want." Lawrence got up and looked down at the foot of his chair, where Perry had sat. "Hey!"

"Where's Perry?"


Perry was actually inside the cupboard at the moment. He waddled over to what appeared to be a wet spot on the wall and knocked three times. The wet spot became a puddle on the side of the wall, slowly materializing into the form of Major Monogram. The man began to speak.

"Glub glub glububglub." Perry looked on in confusion. Monogram looked around at the edges of the puddle. "Glub?" he glubbed. You couldn't tell what he was saying, but it was definitely a question. Monogram looked over to his left and appeared to be talking to someone. He looked back at Perry, then motioned at Perry to jump into the puddle. The platypus did as he was told, even though the puddle was about half a foot in diameter. After making the tight fit, Perry the Platypus was wet, annoyed, and in the tube system entrance to his secret lair. After making his landing into his orange plastic chair, he looked up at the monitor.

"I'm telling you, Carl! These lair entrances are even starting to test my suspension of disbelief. That last one just... defied the laws of God and man in a way I find ridiculous. And I thought the rabbit hole was passable!" Major Monogram was up on the monitor, chewing out a likely innocent Carl. Come to think of it, Perry did not know who installed all the secret entrances into his home. He made a note to figure that out later. Monogram finally noticed Perry, and looked surprised.

"Oh! I'm sorry Agent P, I didn't notice you were there." Perry crossed his arms. He was used to it. Monogram motioned to the photo of Dr. Doofenshmirtz on the right side of the screen. "Doctor Doofenshmirtz has been purchasing seismographs, thermometers, and other volcano-related scientific instruments. What he intends to do with it, we don't know, but as always, put a stop to it!" Perry saluted and headed into his hover-car. The hover-car quickly rushed through a tube and shot like a rocket out of the manhole cover in the middle of the street.


Isabella Garcia-Shapiro was crossing the street, same as nearly every summer morning for the past 4 or so years. As she approached the gate to the Flynn-Fletcher's backyard she was suddenly startled by a manhole cover landing with a clank just a few inches away from her feet.

"Eeep!" She jumped back and then inspected the metallic disc. "Huh." She propped open the gate and took a look at the manhole cover, not sure where it had come from. "That was a tad unusual. Oh well." She walked through the entrance to find her favorite boy (and his brother) getting the supplies ready for today's inaugural creation.

"Hey, Ferb. Hey, Phineas. I would normally ask, but someone already told me what you were doing today." Isabella joked as she walked into the backyard, getting the boys' attention. Phineas chuckled.

"Good morning, Isabella! You excited? I mean, we only get summer... maybe 3 months a year!" Isabella looked like she was about to say something, but Phineas cut her off. "Oh, boy! Obviously I'm excited. You have any ideas for the rollercoaster this year?" Isabella once again began to speak, but Phineas clearly had a lot on his mind. He walked over to his computer desk to order supplies. "I was thinking we could build the whole thing out of metal this year, maybe even take it underground, if we can get the permits for it!" Isabella finally snapped at him.

"PHINEAS!" Phineas stopped talking and gave the girl his attention. He scratched the back of his head.

"Oh, sorry. Got carried away. What do you think?"

"Well," Isabella began, "I wanted to join you and Ferb today but my Mom's going to the airport to pick up my Dad, and I want to be there when he arrives, since he's been gone all year. You're not upset, right?"

"Of course not! Family comes first, you know. It would be worse if you didn't." Isabella sighed in relief. Phineas thought for a moment. "I would still like to involve you, but the airport is all the way on the other side..." Phineas suddenly perked up "... of town! Ferb, I know what we're gonna do with the rollercoaster this time!" Phineas put his arm around Ferb and pulled a map of Danville out of Ferb's breast pocket. He folded it out and dotted a line across the entire perimeter of the Tri-State Area. "We'll make a rollercoaster-based transportation system! The fastest Danville's ever seen! That way, we can pick up Isabella and her family on their way back from the airport!" Phineas was practically cackling with brainwaves. Ferb and Isabella took a few steps back, as his rambling became ranting. "Yes, with this rollercoaster, we're going to make congestion a thing of the past, all over the ENTIRE TRI-STATE AREA!"

Isabella took a moment to collect herself. "Well, we were taking a bus since the car is getting repaired."


Perry hadn't quite arrived at Doofenshmirtz' lair, but he felt a chill run down his spine. His hovercar approached the Doofenshmirtz Evil Incorporated building as the familiar jingle played, seemingly from inside his own head. Perry tried to jump in from the skylight, but the skylight flipped around repeatedly until finally flinging him directly into a grill. The top of the grill shut over his head, forcing him to look out the smoke vents. Doofenshmirtz slowly approached from the darkened corner of the room, standing next to a large, liquid-cooled laser. "Ah, yes. Perry the Platypus. How nonseasonal of you to arrive..."

"And by nonseasonal... I MEAN PERFECTLY SEASONAL!" Heinz' voice raised as he ended his introduction. "I suppose you're wondering what this doohickey is." Doofenshmirtz gave the laser a slap on the side. It faced upwards and fired. "Oh, boy. I hope that didn't hit anything important. No matter." He nodded his head from side to side. "It wouldn't effect most planets anyways. You see, Perry the Platypus, this is the overcook-inator! As you may recall my brother, Roger is the mayor."

Perry gave Doof a nod.

Doofenshmirtz continued. "Alright, you do recall. So, for the first day of summer the mayor is hosting the "Picnic in the Park" celebration. I figured, what better way to start the summer by just tampering with my brother. No reason really, I kinda..." Doofenshmirtz struggled to find the words "... don't know how to make this 'take-over' material." He emphasized with air quotes. "The plan is, just as the food comes out, I will zap it with this beam, instantly causing it to become all burnt and gross. In the case of cold food, it will probably just make it... weird." Perry gave Heinz a questioning look. "Have you ever had a glass of hot Kool-Aid? Never mind." Doofenshmirtz waved dismissively at Perry as he surveyed the park from his balcony. "The party starts, and then comes to an immediate screeching halt, at noon today, so we have a while." he dragged his sofa and TV stand into Perry's field of view. "Up for some morning news while we wait?"


Phineas, Ferb, Buford, and Baljeet had gotten well into their work on the transport system. Phineas was calmly reading blueprints and directing the others operating equipment on the tracks. "Well, if we want to make the circuit by the time Isabella's dad shows up... we're on schedule." Phineas looked up at Ferb. "You think we can hammer out some stops along the way? I'm thinking it would be nice to go to the park for that picnic thing." Ferb gave Phineas a thumbs up and disappeared down into the tunnel they had dug as the entrance. Phineas followed him down into the tunnel. The tunnel became a room large enough to house the start of the tracks. Buford and Baljeet were riding a construction cart, building the track as they went along. There was a drill for digging in the front. Phineas walked out on the track to join the two.

"Maybe I should have brought an umbrella or something." Baljeet observed, dirt falling on their heads. Phineas and Buford nodded in agreement. Ferb appeared above them from a smaller tunnel he had just drilled, handing the three ponchos. "Thank you, Ferb." Baljeet waved at him. The three sat back and let the machines do the work as Phineas used a tablet to chart the path around Danville.


Isabella and Vivian were in traffic on the way to the airport. Isabella was staring out the window at the people setting up for the picnic. "You think Dad will want something to eat?" She asked. Vivian checked the time on the dashboard. "We could grab some food at the park with the neighbors." She looked at her mother expectantly.
"You know, that's actually a good idea. Sure. Is there a bus going there from the airport?"

Isabella nonchalantly waved a hand. "Phineas told me he was gonna take care of it," she said, a little wistfully. "So I'm not too worried."

Isabella's mother thought about the statement for a second. "Phineas Flynn?"

"Yeah."

"Is going to arrange transportation for our family?"

"Yeah."

"From the airport... to the park?"

"Yeah." Now Isabella was confused.

"How?"

"They're building a rollercoaster. Honestly, it's not THAT hard."

Vivian wasn't really sure how to respond to that. It seemed like from time to time Isabella would imply that Phineas and Ferb were a couple of geniuses, and engineered marvels of the modern world. She thought it was probably just her crush on the former of the two exaggerating her imagination, but she was 14 now, so it didn't make sense to just tolerate it any longer.

"Enough of that, Isa! You're a nearly a woman now, it's okay to be a kid now and then, but this... just doesn't make sense."

Isabella recoiled a bit in her seat. "Huh? What's so nonsensical?"

"Phineas Flynn doesn't REALLY build rollercoasters, Phineas Flynn doesn't REALLY go to the moon, right? You sound almost like Candace!"

"But... he does! You've seen some of the stuff he's made! What about the massive birthday cake in our backyard every year?"

Vivian paused. "You mean the Flynn-Fletchers baked that themselves?" Isabella nodded as if it was obvious.

"Yeah. They built that laser light show for the block party a few years back, they built that restaurant that opened up in the neighborhood for one night, OH! And Phineas found your wedding ring with those X-Ray glasses!"

Vivian was luckily stopped in traffic, but internally she was experiencing a weird mixture of emotions. "Isn't all that... kind of dangerous?"

"Mom, I have a Fireside Girls patch for wrestling an alligator. You were cool with that, right?" Vivian realized she probably ought to go to more of the girls' meetings. Isabella looked at her phone as she received a text from Phineas: Almost finished with the track to the airport. Anything we need to consider? Isabella thought for a moment, and sent back a response: Dad's probably going to be jet-lagged. Could you make a slower track from the airport to the picnic? Then we could all eat together :) She got a response seconds later: Eating together sounds good, I'll tell everyone. She quickly typed out a response:

Thanks, Phineas 3

She decided to delete the last couple of characters before sending the message.


Phineas looked up from his phone at the others sitting in the car with them. "Hey, can we accommodate a second, traditional set of tracks? Isabella realized not everyone's going to be up for the intensity of a rollercoaster, and her dad's gonna be tired from flying."

Buford crossed his arms with a huff. "Why are you bending over backwards just for girlie, Phineas? If someone doesn't want to ride, they don't gotta ride!"

Phineas gave Buford a disappointed look. Ferb appeared the ceiling once again and jumped down into the cart. Phineas shrugged his shoulders, and was about to say something, when Ferb interrupted. "She gave us the idea in the first place." Phineas nodded in a agreement.

"Besides, Buford, you wouldn't even be able to build this kind of thing without our knowledge." Baljeet chided. Buford socked him on the arm. "Ow! What was that for?"

"Bein' right, I guess." Buford mumbled. Phineas hopped off the cart into one of Ferb's side caves to go start on the alternate tracks. Work continued until they made their way around the town. The boys built stations every once and a while, so there was one at city hall, one right next to the Flynn-Fletcher house, one at the airport, one at the park, and so Candace could make it later, they built one at the Johnson's house. The coaster this time was fairly standard, but people really enjoyed using it to ride to the picnic. It was hard to see in the cave tunnels, so the cars had headlights.


Candace was sitting next to Jeremy, having finally finished browsing possible venues for their wedding. They had decided on a little church in a quiet corner of town. Since it was near the lakefront, all that was there were a few houses and a nice restaurant. Jeremy closed his laptop and looked over at his fiancee. "Alright. Seems like a nice place. You want to head out to the picnic? You look like you could use a break."

Jeremy's concern was not unwarranted. Candace's difficulty picking a place mostly stemmed from her vision of a perfect wedding. Jeremy was patient with her and let her be in charge of most of the details. Jeremy stretched as he got up from the table and opened the door to let some fresh air in. He picked up a bag by the door. "Oh, man, what are those guys up to now?" A station for the coaster transport system was sitting right on the sidewalk. Candace came outside and took a look at the device.

"The boys said they were building a rollercoaster. This just looks like... a box."

Jeremy held Candace's hand and led her inside. They took seats in the cars. "Well, this does look like a coaster car, but how will we get on the -"

Jeremy was cut off when the track beneath them began to sink. A small screen appeared in front of the two of them, with two options:

SAFE

FUN

Candace tentatively reached for the SAFE option, but the sudden jostling of the track caused her finger to slip and hit the FUN option. Jeremy chuckled at her. "Feeling brave today, are we?"

"Not especially." She gulped. Then they launched off underground towards the park at a high speed, Candace gripping the bar tightly and Jeremy reaching up into the air.


Isabella and a anxious Vivian were waiting for their passenger to arrive. Vivian was still shaken by the assertions that Isabella had recently made. The passengers flooded out of the gate, and luggage was coming down the baggage claim. Joseph came out of the gate, dressed in a military suit and cap.

"Vivian! How are you doing, dear?" He quickly embraced his wife, giving her a kiss. He turned to his daughter. "Isabella!" He effortlessly swept her up in a bear hug, kissing her on the cheek several times. "Look how you've grown! You look beautiful!" Isabella blushed from embarrassment.

"It's good to see you too, dad, but could you stop crushing me?" Joseph put Isabella back down. Isabella heard a chuckle from behind her father. She peeked behind her father's large frame to see a young boy, about her age, carrying her father's suitcase. He was dressed in a gray sweatshirt and a pair of black jeans, wearing a cap labeled "U.S. Navy Corps".

The boy stepped forward and offered Isabella his hand. Isabella, confused, grabbed it and the two shook. Joseph seemed to have a moment of clarity and then turned to the two. "Oh! I'm sorry, I forgot to introduce you to our new ward. Isabella, Vivian... this is Flint."

Flint smiled at the two of them. "Howdy. It's good to meet you finally meet you two. Sarge talks about you all the time." He extended his hand to Vivian and stiffly shook with her as well.

Isabella looked up at Joseph. "This is the boy staying with us this summer?" Joseph nodded and continued to familiarize them.

"Flint is one of the boys that served under me on the USS Nimitz during our tour. Real brain for engineering, but he's a state ward, so I offered to take him in for the summer between our tours so I could guarantee him a decent place to live."

Vivian looked down at the kid. He couldn't have been more than 15. "Isn't he a little young to be a member of the Navy?"

"Yes," Flint flatly stated, "Yes, I am." The four sat down as Flint tucked into his luggage and pocketed a small metal pen.

"So you're a naval engineer? Cool! I know some guys that could use your skill-set if you're game." Isabella started. Her parents gave her a strange stare. Joseph turned to Vivian and whispered in her ear.

"Is she still on about that Phineas kid and all those crazy things she does?"

Vivian shrugged and leaned into his ear. "Apparently, she's not joking. We talked about it on the way here and it turns out they've been doing this stuff all summer for the past 4 summers."

Joseph seemed visibly frazzled by this, which probably meant it was the least opportune time for one Phineas Flynn and one Ferb Fletcher to show up by their chairs. They hurriedly motioned everyone out the door.

"Hey, welcome back to the States, Mr. Garcia-Shapiro! We've arranged transportation for you outside!"

Before the Garcia-Shapiros could protest, Isabella had grabbed the luggage and along with Flint headed out the door. The six of them piled into the cars, with the baggage in the back.

"Wha- What the heck is all of this?" Mr. Garcia-Shapiro motioned to the complex cave system around him. A monitor once again came down from the ceiling, once again displaying the options SAFE and FUN. Isabella leaned forward.

"I got this!" She tapped SAFE. Ferb looked a little disappointed. Isabella's parents looked confused. Flint leaned back in his seat, putting his arms behind his head, seemingly bracing for impact. The coaster launched at a reasonable speed on a mostly flat track towards the park.

Flint now looked disappointed. "So this is the work of the great Flynn-Fletchers?" Phineas chuckled.

"It's labeled 'safe' for a reason. I can take you on the 'fun' route later."

Phineas paused for a moment.

"Also, who are you?" Isabella quickly introduced the brothers. Flint shook their hands.

The Garcia-Shapiro parents were still processing all these events.


Doofenshmirtz and Perry were intently watching "The Dr. Zone Files" when a timer went off on Doofenshmirtz' cell phone. The episode was so engrossing that Doof was startled by the timer. "OOH!" Doofenshmirtz excitedly went over to his inator. He looked through the scope at the tables carrying the mass of food for the summer picnic. He was just about to fire when Perry decided to act. In the time that they had been waiting for the picnic to start, Perry had been making a small pile of kindling from the materials in the grill. He pulled out a match from his hat, and lit the pile. Smoke emitted from the grill. Doofenshmirtz looked over at the grill, which was in his lab. "PERRY THE PLATYPUS?!"

Doofenshmirtz thought for a moment. Then he began to panic. "That's not meant for indoor use!" Doofenshmirtz went to grab the grill by the handle, but Perry grabbed his hand and stuck it through the small hole in the grill's smoke vents. Doofenshmirtz hand was stuck. "Huh." Doof tried to remove his hand to no avail. He looked down at the floor and grabbed a wrench. "Too bad, Perry the Platypus, but I can still reach the fire button!" Doofenshmirtz threw his wrench and it hit the overcook-inator. The inator changed direction towards out of town and fired.

Doofenshmirtz looked displeased. He turned towards Perry and shrugged. "Eh, so I missed. What could it possibly have hit?"

It could have possibly hit Mount Danville. What was previously a normal incredibly large mountain was now an incredibly large volcano. Doof looked out at the mountain. He turned his head to Perry. "Alright, since we now apparently have to save the Tri-State Area from an erupting volcano, I think it would be reasonable to let you out." He let Perry out, who gave him a slap on the face before he dived into a pile of components desperately looking for something to stop the flow of lava as the volcano began to overflow and begin dripping down towards the Tri-State Area. "Well the lake is on one side, so that's probably safe enough, but on the other side is THE ENTIRE TRI-STATE- sorry, the whole city!"


The Garcia-Shapiros, the Flynn-Fletcher brothers, and the Flint all got out of the rollercoaster car at the park. The Garcia-Shapiro parents were still gathering their thoughts as their daughter grabbed the bags and got outside the car. Having prepared those thoughts, Mr. Garcia-Shapiro put his hands on his daughters shoulders and she faced him.

"Isabella, I know you thought you had told us about all this stuff, but we thought you were... kidding. Seeing it now, I- " He looked down at the tunnel they had just emerged from. His shocked expression turned to one of anger. "I think-"

Flint pulled the pen out of his jacket pocket, interrupting Joseph. "Excuse me, Isabella." He put the pen in front of her face, facing her father and mother. A flash emitted from the pen. Vivian and Joseph waited for a moment, and then blinked.

"How did we get here?"

At that moment, Candace emerged, Jeremy in tow, from their station. Candace saw the boys standing with their friends, and then turned towards Jeremy. "I've finally got a chance! It looks like the Garcia-Shapiros have already seen it!" She pulled her hand from his and began to rub them together. "But just in case... I better go get mom." She sprinted off without a moment hesitation. Jeremy sighed and pulled a blanket out of his bag.

"I might as well save us a spot." He grumbled.

Candace rounded the corner of one of the food stands and almost smacked into Linda, who was with Lawrence. "Easy, there, Candace. What's going on now?"

"Phineas and Ferb, they built-" She caught her breath. "- a rollercoaster! Again! But it runs under the town and it has a safe option and a fun option and I picked the fun option and I think I'm gonna hurl and there's no way they were allowed to dig a giant tunnel under Danville and there's no way they did it safely and Isabella's parents have already seen it but LOOK LOOK LOOK!" She began to drag Linda around the corner.


The lava was quickly approaching the town. Roger Doofenshmirtz, who was up on a large stage, was the first to notice it was coming towards them. "EGAD!" He screamed, "Mount Danville, which was not previously known to have been a volcano, is suddenly a very active volcano! Everybody, RUN!" It was at this moment, as the lava reached the edge of town, that the ground beneath it began to give way. The tunnels Phineas and Ferb had built collapsed, causing the lava to spill into the moat formed by the pits. It surrounded the whole city, but it didn't touch anything. The lava was melting roads and structures at the edges of town, but all the people in town were safe. All the people who had been watching the lava flow sighed in relief.

Candace came around the corner, Linda in tow, and looked upon the destruction wreaked by the lava flows. Linda gasped. "Did Phineas and Ferb do THIS?" Candace put her arms to her sides.

"No, mom, what they made was actually destroyed by the lava."

Linda once again donned a nonplussed expression. "Well, I guess that's much ado about nothing, as always. There's no use worrying about that volcano right now, so let's grab some food and all sit at the spot Jeremy appears to have picked out."

Jeremy waved at them from some distance.


"Well, that problem appears to have solved itself, Perry the Platypus. And what's more I can hit the beam again and actually hit the food this time!" He realized there was nothing else around him to throw. Perry then jumped up and smashed Doof's face with a fist, causing him to stumble backwards and hit the overcook-inator. Both plummeted off of the building. "HA! I've prepared for this, Perry the Platypus!" He pulled a string on his labcoat and out came a parachute. The overcook-inator hit the ground and fired at the parachute, causing it to melt into thin air. "Huh. You can't prepare for everything, I guess." He began to fall at an increasing speed as Perry dove off the balcony, pointing his glider in the direction of the park.

"CUUURSE YOU PERRY THE PLATYPUUUUUUUS!"


Candace was sitting at the large picnic blanket, eating some pork roast with the rest of the Flynn-Fletchers, the Johnsons, the Garcia-Shapiros, and Flint. Flint walked up to her, introduced himself, and shook her hand, then sat back down next to Phineas. She turned towards Vivian. "So you and Mr. Garcia-Shapiro saw it, right?" She asked.

"Saw what?"

"The rollercoaster! That's how you even got here!"

"Candace, I don't even remember how we got here. I suppose traffic really is that boring sometimes."

"But- but- but-" Candace continued stuttering as Flint leaned over towards the brothers and Isabella.

"You can thank me for that one later."

Isabella and the boys exchanged confused glances, then Isabella looked down at the teal platypus that had just walked out from behind the tree they were under. Isabella and Phineas both reached down to pet him. They both put their hands on him, but Isabella quickly retracted hers and blushed.

"Oh, there you are, Perry." Phineas picked Perry up, put him on his lap, and began to rub his belly. Buford and Baljeet sat down with their food and began to chat with the other teenagers. All of them began to talk and laugh amongst themselves. Phineas turned to Flint.

"So what was that pen thing you used on the Garcia-Shapiros earlier?"

"Oh, uh... it was to make them forget! You always make them forget, right?" Flint twirled the pen-device around in his hand and tucked it into his jean pocket. "Enough about me, though. I've heard a lot about you guys, and I'm something of a engineer myself."

Phineas put his arm around Flint, who seemed a bit startled by the sudden closeness. "Well that's great! You should come over with Isabella tomorrow! She's always hanging with us. She's the best."

"But I didn't have-" Flint stopped himself. "Never mind. I'll take you up on that, Flynn." He laid back on the grass as he pulled out a cell phone and preformed a quick internet search:

Phineas, unaware, leaned back and looked off into the sky. "Something tells me this summer's going to be a bit out of the ordinary."

Ferb cleared his throat. All the teenagers gave him their attention. "Well, with us, I think there's no such thing as an ordinary day." He silently tore into a chicken leg as the families began to discuss their plans for the summer.


A/N: There you go! The first chapter of what I have planned as a pretty extensive fic. The whole thing's going to be pretty episodic, so I'll try not to leave you on cliffhangers. Be sure to review and tell me how the writing is. Updates are probably going to be bi-monthly, weekly if I have a break from school. I'm really hoping to nail comedic timing with this one, so I'm reading a lot of Terry Pratchett. Oh, and for a warning, there will be shipping nonsense, but it's mostly gonna be the canon ones. I'm definitely writing Phineas and Isabella an arc, but I'm debating if I should do the same for Ferb and any of his potential interests. There is a gag I thought up based on an observation a friend made, but it might not be a "story" per se. Just a little Ginger and Baljeet too. If anyone wants to beta/edit future chapters for me, DM me, it really helps to have lots of eyes on writing.

NEXT TIME: QUALITY UNCONTROLLED

Phineas and Ferb design a wedding dress! Flint makes a friend, and develops a feeling!
