Move over, Dav Pilkey, it’s George and Harold’s turn to tell the tale of the all-new superhero who’s faster than a speeding stroller and more powerful than diaper rash. Make way for Super Diaper Baby!

Oh, no! It looks like George and Harold are in trouble again… . As punishment, the boys have to write a 100-page report on good citizenship, and they have been specifically ordered NOT to make another comic about Captain Underpants. So what do they do? They create an all-new superhero … Super Diaper Baby! Super Diaper Baby’s archenemy, Deputy Dangerous, wants to steal his powers and take over the planet. Will the diaper-wearing dynamo defeat the deputy, or is the entire Earth doomed?

This new paper-over-board edition includes a 16-page behind-the-scenes bonus section!
