The sixth book in Dav Pilkey’s best-selling Captain Underpants series, now available in Sound-O-Rama!

George and Harold are up to their old tricks again, and when their latest prank makes a direct hit on school brainiac Melvin Sneedly, he decides to get even! But in the blink of an eye – and the sneeze of a nose – Melvin goes from snooty to snotty, and the Bionic Booger Boy is born! Can Captain Underpants clean up this catastrophe, or will the mucous monster make a mess of things?

The Captain Underpants series is perfect for listeners of all ages. Like the other outrageously funny books by acclaimed author and Caldecott Honor illustrator Dav Pilkey, this adventure is sure to be hours of fun!
