I also feel that Planet Zoo needs some Nocturnal Animals like: Bats, Binturong, Red Wolves, and maybe some Badgers a Nocturnal Animals Pack would be good for Halloween but it probably wouldn’t get done before then.
Thanks for opinions I appreciate itBats would require game mechanics that don't currently exist, I'm afraid. We might see the binturong in an Asian animal DLC at some point, it is a rather popular choice. The red wolf I'd rather skip, since we already have a number of wolves (generic timber wolf, Arctic wolf, and now the dingo).
In a perfect world they might include the kiwi in a nocturnal animals pack, but I doubt it.
