That is awesome, I'm very much looking forward to seeing your zoo appear on the forum this winter
I actually got a vulcano set at the Playmobil store in Dietenhofen for the same purpose: it looks SO cool as an animal hideout and it's got some very unusual foliage and trees. *pretty!*
Expensive set if you get it new, but I gave the dinosaurs to my nephew, so I had an excuse
And the tree house is such a lovely set aswell. Great finds!
