*Note: Noisy Book batteries are light activated, please make sure the lighting is sufficient for this book. This series takes DK's popular Peekaboo books to the next level by filling them with sound! On each spread, young readers search for a lost toy, such as a cute puppy, busy truck, or woolly sheep. There are three or four flaps to look under, and when the right flap is lifted, the lost toy is revealed and an appropriate noise is immediately activated: "Woof! Woof!" "Brrm! Brrm!" "Baa! Baa!" Toddlers will be captivated and delighted by the noisy surprise, and will want to find the right toy again and again. Noisy Peekaboo: Woof! Woof! features five noisy animals hiding under colorful flaps.
