The Adventures of Super Diaper Baby

George and Harold are two amazing kids. Not only did they create Captain Underpants, but they saved the world five times! But once again George and Harold are in trouble with their school principal, Mr. Krupp. After they make a mess in the school gym, they have to write a 100-page report on "good citizenship," so they invent a new superhero: Super Diaper Baby. This is an actual baby called Billy who gains special super powers. 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?
Featuring a special appearance by Captain Underpants, The Adventures of Super Diaper Baby is the hysterical graphic novel tale of the all-new superhero who's faster than a speeding stroller and more powerful than diaper rash.
