6 simple scenes, 6 fairly realistic animal cries accompanied by a background sound (the sound of water ...) It is very easy to turn on the sound, even for a little less than a year, and the volume is not too loud. While the sound of the elephant is likely to scare most fearful, but we could still not do it meow! The animals are: lion, hippopotamus, monkey, elephant, panda and parrot. It is much better than any other audio book collection that I bought (sounds unrealistic and difficult to trigger too great book). I intend to try others in this collection.
