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

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.
