Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy, Part 2: The Revenge of the Ridiculous Robo-Boogers: Color Edition (Captain Underpants #7)

Bionic boogers return in the seventh book in this #1 New York Times bestselling series by Dav Pilkey, the author and illustrator of Dog Man!

George and Harold thought they were beyond boogers. Their new pet, Sulu the Bionic Hamster, had defeated the Bionic Booger Boy, and through the wonders of science, Melvin Sneedly had been brought back to normal (well, almost normal). It looked like their last adventure was actually going to have a happy ending... except for one thing (well, three things) -- the Ridiculous Robo-Boogers. Now George, Harold, and their buddies are on the run -- with the Robo-Boogers in hot, gooey pursuit! Will the boys get away from these gross globs, or will Sulu have to save the day again?

Dav Pilkey has written and illustrated numerous popular, award-winning books for children, including the Captain Underpants and Dumb Bunnies series; Dog Breath, winner of the California Young Reader Medal; and The Paperboy, a Caldecott Honor Book.
