It's playtime with Little Critter--so let the games begin with this delightful board book. Mercer Mayer's popular and mischievous hero has a busy day romping with his dog, his friends, and his sister. There's so much to do, from flying a kite and going on the swings to playing pirates and taking a mud bath. But after all that fun, one very tired Little Critter needs his nap. Sleep tight!
