I wasn't sure offhand what bears live in the Andes, but when I found a pic, immediately recognized Spectacled Bears. I have always liked them.

I don't think it is too out-of-line to suggest these are just an extreme example of how animals generally fail to thrive in zoos.
I do have to say that hedgehogs look better with their spines.
