The first epic English novel by Dav Pilkey!

A highly enjoyable picture novel  - brilliant for reluctant readers! The simple black-and-white illustrations on every page furnish comic-strip appeal. Includes several pages of flip-o-ramas that animate the action. 

Two fourth-grade boys who write comic books and love to pull pranks find themselves in big trouble. Mean Mr. Krupp, their principal, videotapes George and Harold setting up their stunts and threatens to expose them. The boys' luck changes when they send for a 3-D Hypno-Ring and hypnotize Krupp, turning him into Captain Underpants, their own superhero creation.
