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 trampled the terrible talking toilets! They crushed the crazed cafeteria ladies! They punished Professor Poopypants! And they whacked the wicked Wedgie Woman! What task could possibly be worse? This one is worse: As punishment, they have to write a 100-page report on 'good citizenship,' and they have been specifically ordered NOT to write another book about Captain Underpants. What are two comic-book creative geniuses to do? Meet Super Diaper Baby -- the most powerful peewee to pack a punch. With Pilkey's typical Captain Underpants over-the-edge humor, Super Diaper Baby will have readers laughing until soda comes out of their noses. George and Harold have created a diaper-clad baby superhero who accidentally falls out of a window and lands in a tub of Super Power Juice. His arch-enemy, Deputy Doodoo, wants to steal Super Diaper Baby's powers so he can take over the world. Will Doodoo win? Is planet Earth doomed? And does this sound like a report on good citizenship to you?
