My son collects audio books where one uses a chip by page to trigger the music. So I have in different collections and those in Grund are the best. This book therefore has excellent qualities pages, songs are melodious voices sing well (unlike those of Thomas Youth are a catamaran), the batteries last longer than others, but above all, they are the least expensive! !! In it, there are the songs: it was a small ship, little rabbit was very sorry, brother Jacques and make the puppets, the spider Gipsy and Pirouette Peanut. I highly recommend it! This is a great gift for toddlers;)
