General Pepper contacted StarFox Headquarters and asked Fox McCloud to go on another mission but at a different destination. Krystal wants to accompany Fox to adventure with her mate so Pepper accepted the offer and told them their venturous destination.

Andross asked General Scales to head for Corneria to pick up Wolf O'Donnell for a reforming interrogation. Scales agreed to get Wolf to be brought back and ready when the rogue mercenary is part of StarFox.

Fox McCloud and Krystal landed on a different world, a big seaside beach near the town. They went around asking for the Mayor and were directed to the town hall to meet the owner of the town. Fox and Krystal meet with the mayor of the seaside beach town and asked about the town's history. The mayor started telling the town's historic mysteries of what's in the water below.

While Fox McCloud and Krystal listening to the town's mysterious history, General Scales visited his home and the Sharpclaw Tribe to make a few arrangements before returning back to the Subspace Headquarters.

The Sharpclaws voted a new leader hoping to make peace arrangements with the other tribes on the Dinosaur planet. Scales went to visit the Earthwalkers and apologized for the tyranny events that he had done, so they accepted his apology and became better friends to the reformed General Scales.

Fox and Krystal rented a speed-boat at the pier and went to go scuba diving to explore the underwater mystery. A sudden tidal wave appeared to knock off the boat riders; Krystal was safely spared on the speed-boat, but Fox McCloud was plunged in without his scuba gear.

The drowning Fox McCloud sees a mythical figure approach to rescue and change the slave-collared hero into a merman, and suddenly fainted after his transformation. Fox awakens in a submerged hotel room and saw a blue-tailed Wolf merman sitting on a chair near the bed.

Fox noticed the diving suit he wore was gone and introduced himself to the Wolf merman. The merwolf Maku, has heard of the famous Fox McCloud and introduced himself to Fox as the Prince of Laguna, the underwater kingdom and city.

Fox McCloud told the merman Maku that he arrived on the surfaceworld with Krystal to learn of the seaside town's mysterious history. So Prince Maku told Fox about his father's problematic past with the town above... a stolen ancient artifact.

Fox McCloud asked merwolf Maku a tour around his underwater kingdom of Laguna and a visit to the palace, so Maku agreed to his request and the mermen swam out of the hotel to explore the city of Laguna.

Krystal went back to the seaside town and barges into Town hall to ask the mayor about the stolen artifact after hearing Fox McCloud survived the sudden tsunami. The Mayor hid his corrupted ideals after receiving the ancient artifact from the exiled seawitch.

Krystal rented a room at the town's hotel and contacted General Pepper about the truth about the Seaside Town dark mystery. Fox McCloud meets with the King of the underwater kingdom of Laguna and asked the history of the ancient artifact.

Krystal wears the Janitor uniform to prepare a confrontation in the Seaside Town Hall. Fox McCloud told the King and his new friend about the brave space adventures with his StarFox crew, so the King trusted Fox to do something important before letting his son join StarFox.

Krystal returned to the city hall and asked about the deal with the Sea Witch, so the mayor spoke to Krystal again and was unaware of Mike hidden in the remodeled office. Furious townspeople have launched a riot demanding that the corrupt mayor return ancient relics to the underwater kingdom.

General Pepper's Police arrived and arrested the fleeing Mayor with the stolen artifact; Krystal brought the ancient artifact to the waiting King and Fox McCloud became a land walker again which embarrassingly grabbed his uniform from Krystal.

Prince Maku said goodbye to his father as he changed to bipedal form before entering Fox McCloud's starfighter.

Fox McCloud and Krystal returned back to the StarFox Headquarters with a new teammate. Maku met Andross while Falco asked Slippy to build a new battle visor and starfighter for their new teammate.

Andross asked Fox to let Maku temporarily sleep in his apartment home for couple weeks while he build a modded apartment home for Maku; Andross told Fox McCloud that he added the Jaccuzi and Swimming Pool centered from the Apartment homes for them to relax and exercise.

Andross opened a portal to Corneria for Krystal to go shopping with Maku to find clothes for him to wear. Fox McCloud takes a bath in his bathroom and noticed his legs & tail fused into an orange-colored fishtail again... he somehow realize he absorbed a little magic from the King's Trident.

When Andross summoned a security monitor to check on Fox, he was shocked to see the transformed merman Fox in his bathtub; his jaw dislocated and landed on top of Slippy, and Peppy noticed what Falco was pointing at. Scales in his apartment is also seeing what happened to his brother Fox.

Fox McCloud still in his merman form was carried to his bed by Falco and Scales while Slippy uses his new modded scanner to scan Fox's merman body. Krystal asked Andross where the boys went, so Andross expanded his monitor and showed both Krystal and Maku the shocking event in Fox's apartment.

Macku went to Fox's apartment to comfort his transformed roommate while Slippy rushed to his crafting lab to create a modified tail ring for Fox McCloud. Fox told Macku that he received a little magic from the trident of the underwater King.

General Pepper contacted StarFox Headquarters to congratulate Fox McCloud and Krystal of their mission, but instead shocked to see merman Fox on the bed. Macku apologized for what happened to Fox before they departed from the Seaside Town.

General Pepper told Macku that the King of Laguna became a temporary Mayor of Seaside Town, and congratulated the young Prince for joining StarFox. Macku asked Fox to dry his merman fishtail so it'll revert back to bipedal legs and foxtail.

Slippy Toad gave Fox a magic-modded tail ring to slip on his foxtail; he told Fox McCloud that it's effects inhibit the changing when he is taking a bath/shower, but not effective in saltwater.

Fox McCloud dressed in a clean uniform, heads to the Launch/docking Bay before going to Corneria. Wolf O'Donnell entered the main room to chat with Andross, but instead saw the young Prince receiving his gear and gadgets from Slippy.

Wolf met Macku and heard the embarrassing sea story of what happened to Fox McCloud. Wolf O'Donnell asked Andross if he built the Virtual Dome, so Andross told Wolf the room is available and ready for simulation exploration and battling.

Remembered Maku's story of Fox McCloud's sea adventure, Wolf sets the simulated Laguna in the Virtual Dome. Wolf O'Donnell starts training Maku on learning to defend his home against the Shark-Raiders.

Fox McCloud entered the Virtual Dome to find Wolf and Macku shooting at the simulated enemies. When the simulated raiders were defeated, Macku showed Wolf the simulated Laguna of the underwater kingdom in the Virtual Dome.

When Macku brought Wolf to the simulated Palace Courtyard, he trained the ex-mercenary how to wield a powerful Trident. Fox McCloud jumped in the training session since he wielded Krystal's staff before.

As Andross watched Macku trained the StarFox mercenaries, the merfolk citizens of Laguna watched the holographic live-view of their Sea Prince training the heroic land-dwellers.

Krystal, Falco, and EX-General Scales entered into the Virtual Dome to watch Fox McCloud spar with Macku in the simulated palace courtyard. Krystal was thinking of her weaponary staff so she could train with Fox and Macku.

After training at the Virtual Dome, most of the StarFox crew went to relax at the Jacuzzi and Pool. Fox McCloud, Krystal, and Scales are relaxing at the Jacuzzi while Wolf and Falco were gawking at Macku's mythical sea-form in the swimming pool.

After the team had dinner, Andross told Fox McCloud that every apartment has a sofa that folds out into a bed with a memory-foam mattress. Fox changed to his pajamas while Macku wanted to try sleeping in his merman form on the sofa-bed.

While Macku is sleeping on the sofa-bed, Fox McCloud slipped off the tailring from his foxtail and covered his legs with a damp towel to sleep in his merman form.

Morning came when Macku awoke to see Fox McCloud still sleeping on the bed in his merman form. Macku grabbed a dry towel from the bathroom to cover Fox's dampened fishtail.

Andross watched Macku covered Fox's dampened fishy merman-tail with a dry towel, so Andross asked Scales to carry-and-drop the sleeping Fox McCloud into the swimming pool. "That'll wake up the stubborn Fox!"

General Pepper called StarFox and asked Fox McCloud to go undercover covert mission. Scales asks why Fox couldnt bring his teammates along, so Pepper replied that fox will call reinforcements if he gets in deep trouble.

Fox McCloud dried his body & reverted to normal, reslipped his tailring while dressing his uniform on his body, eaten breakfast, and went to the launch bay to head for his new mission destination.

Macku asked Andross to follow Fox McCloud to the new mission, Andross felt worried about his son McCloud let Macku sneakily follow Fox to the next destination. Slippy Toad told Macku that he can use the camouflager on his starfighter, so Macku felt excited and headed out to follow behind Fox.

Fox arrived at his mission and changed to his Janitor uniform to enter the building undetected. Macku arrived close by and secretly contacted Andross to see what enemies Fox McCloud will be facing.

Janitor disguised Fox picked up a broom and swept through the hallways till he stumbled upon a prison hall with lots of male & female abducted hostages. Outside the building, Andross told Macku the new enemy was from a different world, transformed the hostages into merfolk, and sold as sex slaves.

Janitor Fox watched the captors stripped the clothes from each hostage, dropped them into a water-filled stasis tube to be forcibly transformed to merfolk, and put slave collars on the transformed hostages. Fox was about to rescue, but got knocked out by a looming shadow.

Macku was stunned to see an octilean, and watched him carry KO'd captured Fox to the trunk of the car with his henchmen following. Macku jumped into his camouflaged starfighter to follow the enemies.

Fox McCloud awoke to face his sea-creature enemy and noticed he's roped-and-chained at the pier surrounded by the cunning henchmen. Fox chatted with his captor to know the enemy's intentions, but was muffled and dropped into the saltwater ocean to drown.

Fox McCloud was lucky to be thrown into the sea to transform into a merman again but still tied-up while sinking to the sea floor. Macku dived in to rescue Fox, but met an unusual metallic ally... Sky-Byte!

The former predacon, Sky-Byte helped Macku rescue Fox McCloud and told his story to the StarFox mermen of the recent events at the Dark Laboratory. Fox McCloud pieced the events together and learned the enemy's true intentions for the abducted merfolk slaves.

Sky-Byte also told Fox what happened to the trespassers when they tried to exploit the enemy's plans to the whole universe, but were captured and thrown into the sea to drown in their watery grave.

When General Pepper's soldiers and the other StarFox members arrived, Fox still in his merman form, shared the strategic plan to infiltrate the laboratory. Slippy placed camo-patches on the soldiers so they can enter undetected and rescue the hostages.

Fox McCloud reverted to normal, re-entered the laboratory to bait out the enemies. Macku, Falco, and Scales rushed to the Stasis chamber to rescue the transformed merfolk hostages.

The camouflaged soldiers rushed through the hallways to KO and drag out the baited henchmen. Krystal wandered around acting like a scared hostage was finding the sea-creature enemy.

Fox walked through the hallways to find the cunning octillean, but instead heard Krystal's scream and rushed to rescue her. Krystal was stunned and easily captured by the cunning Octillean, and was carried to the stasis chamber to be transformed into a mermaid.

The cunning Octillean brought captured Krystal to exit the laboratory, but was surrounded by StarFox crew members and the un-camouflaged soldiers. The Octillean knew that he was defeated, released mermaid Krystal to Fox McCloud, and was detained with his tentacles tied together.

Fox McCloud carried mermaid Krystal to his starfighter, and the StarFox crew headed back to the Subspace Headquarters. When they returned, Macku went to the Virtual Dome to contact his brother in the simulated Laguna palace.

Slippy Toad entered the virtual dome to see what Macku's submerged home looks like. Macku told his brother of the mission and destination that he went through, so he asked his brother for the potion recipe to reverse the mermaid effects.

Macku's brother swam off to find a certain book that has the reverting recipe. Fox McCloud enters the virtual dome and hands Macku a training staff to spar with while waiting for his brother with the recipe.

The young wolf returned back to the courtyard with the potion book to see his brother spar with Fox McCloud. Slippy walked to the holograpic merboy and asked about the land-dweller potion, so the young prince flipped the pages to the recipe for Slippy to write down before crafting another tailring.

While Fox was still training with Macku and didn't notice his young brother was watching, Slippy told the young Prince what happened to Fox McCloud before he crafted a modded tailring. The young Prince laughed at Slippy's embarrassing story of how Andross' dislocated jaw dropped on the technical frog.

Macku introduced Fox McCloud to his young brother while Slippy walked out of the Virtual Dome to create a concoction and another modded tailring for Krystal.

The young Prince told his brother Macku that he shown Slippy the recipe and also warned him when Krystal become a mermaid again when she steps into the bathtub or shower.

Slippy gave Krystal the concoction that reverted her back to normal and slipped the tailring on her feminine foxtail. Fox McCloud and Macku are glad to hear that Krystal is standing up again.

In the launch bay, Andross built/created a space cruiser with a couple ATVs and Water Jetties, and opened a portal to a different destination. Andross asked Fox to have a restful week off at a different world, so Fox McCloud and Macku packed their bags and boarded the cruiser to their destination.
