Madballs [Aargh; Crack Head; Dust Brain; Horn Head; Occulus Orbus; Screamin' Meemie; Skull Face; Slobulus]; truck driver; Tommy; Tyrone; Dawn; Oxford; Chin; Waldo; Lynn; Beauregard; Dr. Viktor Frankenbeans; Simon Snivelitch
The Madballs are accidentally created when falling into RUIN Labs' toxic pond. They quickly befriend Tommy and several other children. Realizing that he is somehow responsible for their creation, Frankenbeans plots with Snivelitch to capture them.
Colonel Corn, a corn cob mutated by the RUIN Labs' toxic pod, captures Tommy and the other children. Colonel Corn explains to them that he has been "corn-sidering" taking over the world. Fed up with his constant corn-related puns, the Madballs defeat him by forcing him to pop his kernels. Corn survives as a cob and watches as Tommy and the other kids eat his popped corn.
