Great, just 3

Of stickers, paper glue, the "costumes", full of cute animals with names that rhyme. What more when you have 3 years? Nothing it seems. My daughter loves and is glued to this book since we have it. Not a day goes by that calls us to make a collage.
50 animals - moderating a little his hardeurs - it allows to make it last long enough (in 2 weeks we have done just half the loan book).

2 small negatives on my side:
1) I would have liked the text lines below each animals are a little more narrative (and less didacticielles the beginning). Thus allowing to "read" the book once all dressed animals. But it did not seem to bother my daughter who likes to see animals that it has already pasted.
2) The Spiral (although very convenient to detach the stickers and clothing precut sheets) that the book is a bit fragile.

But the graphic quality of the work, and fun it provides, greatly outweigh these minor problems. It is therefore recommended warmly.
