An innovative new interactive series with multiple novelties to enjoy—sounds, flaps, and a mirror! This stylish and engaging forest-themed sound book has 5 different noises to captivate babies' attention and stimulate their senses. Once hearing each mystery noise, babies will guess who is hiding behind the sturdy flap before lifting it up to reveal the animal who made the sound. Finally, the giggle-sound ending is sure to get them laughing as they spot themselves in the mirror! Also available: What's That's Noise? Moo!, What's That Noise? Meow!, and What's That Noise? Roar!
