Deep within the dark, wriggly tunnels of the earth lives Harry, a poisonous centipede who loves munching on juicy, crackly things. Even though he has venom to protect him, Harry is not very brave. His mother has strictly warned him about the terrible dangers that lurk outside their nest—menacing flying swoopers, terrifying furry biters, and the most dangerous creatures of all: the dreaded Hoo-Mins! But when curiosity gets the better of Harry and his best friend George, they accidentally squirm their way up toward the light of the no-top world. Suddenly, the two multi-legged buddies find themselves face-to-face with a gigantic, stomping Hoo-Min walking on its hairy-biter feet! Lost in an enormous, scary world, Harry and George must scurry for their lives. They will have to dodge giant shoes, escape from tight traps, and overcome their own fears to find their way back home. Packed with squirmy fun and insect-sized action, their delightful adventure proves that even the smallest creatures can find big courage when they need it most.
