From the author of Owl Moon and How Do Dinosaurs Say Goodnight comes an original series of board books! Meet the hippos—a lovable, zany crew ready to take the youngest reader on a rollicking ride through the world of numbers, colours and feelings. In One Hippo Hops, hippos jump, glide, trot, march and skip their way from one through 10. Featuring Jane Yolen's delightful rhyming text and Vlasta van Kampen's spectacular illustrations, each edition has been designed to appeal to the imagination of infants and toddlers. And with sturdy, board-book construction (complete with rounded edges), these classics will stand the test of time—and teething!
