Why would so much space be dedicated exclusively to sloths? Here's my idea: a Tropical House WE. It could have multiple species occupying certain parts of it.
- Treetops or Upper Halves of Trees/Perches: Birds, namely macaws and toucans
- Middle of Trees or Lower Half: Sloths and small monkeys/tamarins
- Forest Floor: I don't know, maybe tortoises or something?
