Pilkey plays with words and pictures, providing great entertainment. The story is immediately engaging—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.
