One idea that hit me as a potential thing for the game could be the inclusion of some specifically named animals as we go on with the game. This is mainly due to finding my old binder from the original Zoo Tycoon where I'd filled it with a printed out pdf that someone put together about all of the official animals and their specific requirements and remembering the Magnet the Polar Bear there along with stumbling onto a few videos about specific animals such as the Cincinnati Zoo's Fiona...along with maniacs like Stoffel and Ken Allen...and even ones like Harambe.
Having animals that are released that would be unique per zoo (And per franchise), with set stats that could be distributed with some information about the specific animal they're based off of. They'd be set to be untradeable, perhaps having an extra staff building similar to the trade center that could hold them. Perhaps something similar to the zoopedia with a bit of background about that particular animal or just have a bit when they get released. In game, they might have a slight benefit for attracting visitors and couldn't be released or sold, but could go back into storage. Potentially they could be immortal
Basically, it would function similarly to the reward animals for the global challenges, but with a different method leading up to it as some very specific things for the animal. They would still function the same as any other member of their species beyond a locked name there and the inability to sell/trade them.
