The Epic Tales of Captain Underpants in Space

Inspired by their favorite TV show, George and Harold — along with Principal Krupp — blast off to outer space, where an angry toilet awaits.

After George and Harold learn the truth about their mission, Dupe Licitous enlists the entire crew in a quest to repair a rogue satellite.

Everybody on the spaceship has been cryogenically frozen for three months — everyone, that is, except Krupp, who's wide awake and happily in charge.

The crew meets their blue-hued doppelgängers when they crash-land on an alien planet where kids call all the shots.

Melvin isn't exactly their friend ... but it's not like George and Harold can just let him be held captive by diabolical Biglyans, right? Right?!?

Oh, the indignity: George and Harold are forced to perform spa treatments on gigantic Biglyans. Also, Dr. Fitzgibbons reveals a shocking secret.
