Captain Underpants and the Attack of the Talking Toilets
The second book in the Captain Underpants series, this story is about how George Beard and Harold Hutchins sabotage the school's annual Invention Convention, forcing the principal, Mr. Krupp, to put them in permanent detention. They decide to create a comic book about Captain Underpants. But when they try to make copies on the copier that the school braniac, Melvin, designed, their copies become three-dimensional objects. Chaos ensues when the toilets come alive and threaten to eat the school's occupants.
