Britney and Alvin go head to head over superhero costumes.
Brittany questions what Alvin's up to so she confronts him learning he's charging some classmates to secretly show them Simon's inventions. Alvin opens Simon's hidden closet room to surprise them with his super hero costume, but they aren't impressed. Wanting to see "the good stuff," Alvin leads them to the basement. Alvin fails to open another of Simon's hidden areas and the others demand their money back. Brittany's disappointed and reveals she could be a super hero though the others laugh. They create a bet that Jeanette can/can't turn The Chipettes into super heroes. Jeanette expresses her disapproval only to be roped in by Brittany's vision of them stopping crime and saving others. Alvin spies on them and persuades Theodore to snoop around. Unfortunately Theo gets clobbered accidentally when Jeanette lose control during the first test of her flying boots. While Brittany is certain Alvin thinks they have nothing, Alvin actually thinks the opposite and sets out to gather more intel just to misinterpret a comment made by Jeanette. At school Simon agrees to help Jeanette and, in Simon's basement workshop, figure out the problem with her boots. Since Simon helped her, they reach a compromise in which both of their siblings lose the bet and must gallop around class stating "I'm a silly little donkey" while smacking their butt.
