Children will love this book. Fun is coming to the children's room. This interactive board book can hop and croak. When you press the frog's legs into the book, they spring back out and the croaking sound is activated. This way, children from 18 months old can accompany the little frog through the amusingly rhymed story. The little frog goes on an outing. Along the way, he meets the hazel dormouse, who wants to get to the other side of the stream. How great that the frog can hop and croak across the water with her. After he has also made the deer and the little bunny happy, he joyfully returns to his pond. A funny interactive adventure for the very youngest.
