The beloved and bestselling author of Inkheart returns with a chapter book full of mischief, heart, hilarious illustrations, and pet monsters! Goodbye, earthworms. Hello, chocolate cake! Ruffleclaw is a furry red monster who lives under a toolshed, and he's sick of eating bugs. When he decides to move in with a family of humans, he climbs right into bed with a boy named Tommy. Tommy wants to keep Ruffleclaw as a pet, but it won't be easy. Ruffleclaw makes huge messes--he spits, he drinks shampoo, and he eats everything in the fridge . . . along with the plates! Can Tommy teach his monster to behave? Cornelia Funke's signature touch of imagination and humor delights young readers in her chapter books-- Emma and the Blue Genie, The Pirate Pig, and Ruffleclaw.
