Thanks Tim for your feedback.
I know, that these sets are quite new to Germany and with this are not available local outside Germany. Nevertheless I though, that maybe from the littoral states maybe somebody have this set by incident and could provide the number, because I believe it will have a plan included, as I recognized in the past that even in small sets (apart from the specials) there are small plans included.
Anyway. So I just have to wait or just buy it by my own to get the animals and the no. (although my only interest in this set are the squirrels and nothing else, so it might be a lot money to be spent for the small rodents).
