One Saturday morning, Hamtaro was sitting in his cage eating some sunflower seeds. Then his owner, Laura, and her friend, Kana, walked into the room. Hamtaro's best friend, Oxnard, was in Kana's hands. "Hey Hamtaro! How's my little buddy?" In a hamster language humans couldn't understand, he said, "Great, Laura! I bet you had a great day, too." She stated, "Kana and I were assigned to a group project to report on our favorite animal. We decided to go with hamsters. We thought you and Oxnard could hang around us." "That sounds great! I don't know what a report is, but I bet the four of us will have fun."

She took Hamtaro out of his cage and laid her on her bed. The two humans started writing facts about their hamsters. Kana pulled out a book she got from the library. As they were flipping through, she noticed a tear on the inside back cover. Laura noticed a strange piece of paper hiding behind the tear. She took a look at it. "Check out this. 'Hamster. Ham-Ham. Ticky Ticky. Kushi Kushi. Sunflower. Khrrmp Khrrmp. Transform Now!'" Kana asked, "Why do you think someone wrote this down?" "I don't know. I think that...that.." The two girls fainted.

When they woke up, they saw Hamtaro and Oxnard sniffing them. "Laura! You're awake!" Laura was scared. Did her hamster just talk? She looked to her left to see Kana wasn't there. Instead there was a hamster...wearing glasses!? The hamster looked at Laura and said..."How did that hamster get here?" She looked at her hands...only they were now paws. "Am I...a hamster! Kana, it's me, Laura. I think that text turned us into hamsters!" They couldn't believe it. Hamtaro and Oxnard walked up to them. "You two just fainted, started glowing, and shrunk. Then you grew fur." "Hamtaro, how are you talking?" Oxnard replied, "We could always talk. I guess now that you're hamsters you can understand us." Kana stated, "This must be a dream." Laura replied, "No, dreams don't feel THIS real." They walked over to the text. They tried saying the text again. Nothing happened. "How do we turn back to normal." Hamtaro stated, "This is a job for the Ham Hams!" "The ham hams?" Laura asked, confused. Hamtaro said, "Follow me." and the four jumped off the bed. They crawled behind into a little hole.

Laura couldn't believe it. "You mean to tell me you've been sneaking out of the house this whole time!" Oxnard said, "Take it easy on him. Lot's of hamsters do it." Kana couldn't believe Oxnard. The four jumped down the drainage pipe and found themselves landing on the pet dog, Brandy. The two former humans followed the two natural hamsters to a little hole by a tree. The four entered in. They were surprised to see doors in the tunnel. They entered a room to find a bunch of hamsters playing. They all walked over to their new guests. "Hey Hamtaro, who are the new ham hams." Boss said. Hamtaro stated, "I don't know how to tell you this, but these two are the owners of Oxnard and me."
