With their trademark wit and wisdom, Rosemary Wells and Marc Brown present a groundbreaking?and side-splittingly slapstick!?story which introduces the importance of healthy habits. When a fast-food fanatic family of bunnies set out vacation, they pack their RV full of TVs, Jiffy Chips, and Winky Twinks. But when the weighed-down vehicle wheezes to a halt in the middle of nowhere, Farmer Spratt saves the day by showing the Gulps the value of a fresh, home-cooked meal and the lasting benefits of physical activity. The Gulps' transformation is sure to inspire a generation of super-sized kids?and parents?to turn over a new leaf!

The irresistible, ever-curious, and always bestselling Roach returns with a new adventure to the invisible realm that people carry around inside.
