Oh, no! It's not enough that George and Harold have invented Captain Underpants, the greatest superhero of all time, and that they've also saved the world FIVE times! They defeated Dr. Diaper! They punished Professor Poopypants! And they whacked the wicked Wedgie Woman! What task could be worse?!!? This one: As punishment, the boys have to write a 100-page report on "good citizenship," and they have been specifically ordered NOT to write another comic about Captain Underpants. So what do they do? Aha! Meet Super Diaper Baby — the most powerful peewee to pack a punch. 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?
With Pilkey's typical over-the-edge humor, Super Diaper Baby will have kids laughing until soda comes out their noses.
