A very nice book, where a little mouse very curious request to each of his animal friends he has there ... with their layers on every page, a component to open (the layer of course !!). By the way, the child will learn the names of each animal droppings ... (good though it may seem not necessarily essential hee hee), and a nice late ... but what is there so you in the layer of mouse ...? My daughter loves this book and I hope it will inspire him to get to the pot too !!
