The fourth book in Dav Pilkey’s mega-bestselling Captain Underpants series, now available in Sound-O-Rama!

George and Harold are fourth-grade buddies who all love practical jokes. When their latest prank drives their research teacher over the edge, their clueless primary, Mr. Krupp, quickly hires a replacement: Teacher Pippy P. Poopypants. Obviously, George and Harold can’t withstand making fun from the Professor’s ridiculous name. But then the Professor retaliates by forcing everyone around to improve their own names to be equally silly – with colossal effects!

The Captain Underpants series is perfect for listeners of all ages. Just like the other outrageously funny books by acclaimed writer and Caldecott Honor illustrator Dav Pilkey, this experience is sure to end up being hours of fun!
