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

Laugh out loud with Captain Underpants, the #1 New York Times bestselling series from Dav Pilkey, the creator 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?

Now with super-cool foil covers! Shiny! Fun!

Just when they thought they were out, it pulls them back in! Our heroes beat the Bionic Booger Boy, but they forgot about those rascally Robo-Boogers. Join George, Harold, Mr. Krupp, Melvin Sneedly, and Sulu the Bionic Hamster on an adventure that will take them into the deepest regions of outer space and back through time to the mysterious and uncharted world of the day before yesterday! It's a monster-mashin', robo-wranglin', time-travelin', brain-switchin', nose-pickin' good time!
