Move the sliders back and forth in this unique sound book to hear the busy vehicles come to life. From zippy motorcycles and chugging tractors to beeping busses and zooming speedboats, the charmingly illustrated scenes are full of busy vehicles. Each slider has two different sounds on it - move it one way to see and hear one vehicle, then move it back again to hear a different one!
