We have something like that in the Topeka Zoo, a fake rainforest. It's always been my favorite part. ^^ It's in it's own little building, they're lacking in herps pretty bad (they do have some sort of crocadillan(sp?) in there somewhere, that's about it). They do have some cool birds though, and monkeys that kinda run around loose and stare at you from the trees.
On the other hand, you have differnt fingers.
