George and Harold are usually responsible kids . . . whenever anything bad happens, George and Harold are usually responsible! And it looks like they're up to their old tricks again! First, they ruined the school's science fair with a series of silly pranks. Then, they accidentally created an army of evil, vicious talking toilets, intent on taking over the world. Who will stop the carnivorous commodes?!!!? This looks like a job for Captain Underpants!
