Planet Coaster has a Halloween DLC, and I think I'd be nice to have one for zoo as well! At least a Fall DLC that has decor like pumpkins, haystacks, cornhusks, trees with turning leaves. Things to really make a autumn-like feel the the zoo. Then skeletons of zoo animals, spiderwebs, more ambient effects (Lightning), things to really add a scary vibe to our zoos. I don't know what kind of animals would pair well with this DLC, but some suggestions I have are: The Black Rhino, Black Footed Spider Monkey, Sun Bear etc. I'm trying to create a Halloween Town in my sandbox, and these are the items that would help greatly!
