PaRappa and friends scramble to clean up the Fruits Dojo when Chop Chop Master Onion returns to town after a long training journey. However, when he gets back, the dojo falls down, so Chop Chop forces his students to clean up the dojo and to do an impromptu karate lesson, which showed that he was around the world to learn specific techniques. After much pestering from Paula, Chop Chop shows her to do "the Kilimangyro Chop". As she runs home, her friends follow her and find out that she learned it so she could slice oranges to make marmalade.

School elections are coming up, and both Paula and Matt are on the ballot. PJ unexpectedly wins the ballot even though he helped both candidates.

After catching a cold from Gaster, PJ can't sleep, which has an adverse effect on him. What's worse, he starts to grow larger every time he eats. After being sucked into PJ's little world (via his nose), PaRappa and co. try to expunge the Gaster Virus and save their friend.
