About this book

George and Harold’s latest misadventure picks up right where Part 1 left off—only this time the out-of-control Robo-Boogers are back and bigger trouble than ever. With Captain Underpants, Melvin Sneedly, and Sulu the Bionic Hamster in the mix, the boys rocket from school hallways to outer space and even a wacky time-travel detour. Packed with comics, flip-o-ramas, and ridiculous humor, this fast-paced sequel keeps kids laughing while they root for quick thinking and teamwork. Great for elementary readers who enjoy silly jokes, superhero spoofs, and high-energy action.

Setting: a present-day elementary school, outer space, and a time-travel twist to "the day before yesterday"
