Press the button and listen to how the pups communicate: lamb, kitten, puppy, piglet and chicken. NEW: The last double page is a sound game Search & Find. The audio button plays five sounds or melodies randomly, one of the five images. Children have the task of assigning a sound or melody to the right picture. This sound folder has a newly relief embossing on the cover, rounded corners and works with two replaceable pencil batteries instead of the original knob. All audio recordings are of high quality and of course there is also the ON /OFF button that allows the folder to turn off at any time.
