Dav Pilkey Captain underpants and the perilous plot of professor poopyp

Professor Pippy P.

Poopypants is a brilliant scientist, but his ridiculous name means no one takes his fantastic inventions seriously.

And now he's on the rampage.

He's armed with the fiendish Shrinky-Pig 2000 and he's prepared to use it! This is definitely a job for the world's only superhero with Wedgie Power.
