Captain Underpants 02 : Captain Underpants and the attack of the talking toilets

George and Harold completely wreck the school's Invention Convention and end up in detention. While trying to photocopy their latest Captain Underpants comic, they accidentally create an army of evil talking toilets who want to take over the world. It's Captain Underpants (also known as Principal Krupp) to the rescue as he tries to save the world, and Jerome Horwitz Elementary School, from the talking toilets and the really evil giant Turbo Toilet 2000.
