The pranksters
George and Harold love jokes, pranks and making comic books. Their school, Jerome Horwitz Elementary, is run by the mean principal, Mr. Krupp, who hates fun.
Blackmail
After the boys prank a school football game, Mr. Krupp secretly films them and blackmails them into behaving. They must do chores and be perfect students, or he will show the tape to everyone.
The Hypno-Ring
The boys order a 3-D Hypno-Ring and hypnotize Mr. Krupp. They make him believe he is Captain Underpants, a superhero who wears underwear and a cape. Snapping fingers turns him into the hero, and water on his head turns him back.
Dr. Diaper
Captain Underpants runs off to fight crime, and the boys chase him. He walks right into a bank robbery and the lair of Dr. Diaper, a villain who plans to destroy the Moon with a laser. George and Harold save the day.
