CAPTAIN UNDERPANTS AND THE PERILOUS PLOT OF PROFESSOR POOPYPANTS (Book 4)

George and Harold aren't bad kids. They just like to "liven things up" for everybody. Unfortunately, their THOUGHTFUL jokes sometimes get them into a LOT of trouble.

And when Professor Pippy P. Poopypants becomes their new science teacher . . . well, George and Harold almost cause the entire planet to be taken over by a maniacal, mad-scientist guy in a giant robot suit! Who will stop the perilous plot of Poopypants?!!? This looks like a job for Captain Underpants!
