Cute story, but it's been done to death. I think stories like this are a preschool staple, though, and kids in that age range seen to like them for the numerous cute animals presented, and for the highly predictable inevitable ending that they can anticipate with a knowing, barely contained glee.
I teetered between two and three stars for this. As I mentioned, this is an overdone story. On the other hand, the illustrations in this are really rather pretty and complex. As far as this particular manifestation of this story goes, I suppose it's a good one.
