Could we have Wild Animals? What I mean is Animals that randomly appear in the border of the Zoo, like Wild Snakes appearing out from a Jungle Border or a Wild Boar, maybe even a Bear or a Lion, depending on the biome your in. And to add to this, maybe these Animals could be captured and released, or captured and kept in your Zoos (Depending on the Animal captured).
If you don't capture them, (Depending on the Wild Animal) they'll cause panic in your Zoo and scare away guests. So you'll have to capture them anyway.
Maybe even have Birds flying over your Zoos. Maybe even have those Birds land on your Zoo and eventually get scared away by Guests or other Animals. Maybe even get attracted by spilled food and Garbage.
Speaking of Garbage, what if Wild Animals only appear in your Zoos if you have alot of Garbage in your Zoo.
