Here’s an another short devlog of upcoming new features: trash and poop.
Trash

In the next update trash and trash containers are added to the game. When guest consume bought items, they will gain a trash item which they will try to throw away. If there is no suitable trash container nearby the guest will drop it on the ground and make the zoo messy. Workers will clean and empty trash containers as they see fit. The fantasy theme allows for different kinds of methods of keeping the zoo clean of trash. Maybe you want bottomless trash cans or have portal as the trash container which makes the trash someone else’s problem.
Poop

Poop has been a planned and conflicting subject to be added into the game. Poop can be seen as a dirty and disgusting feature and many games choose to ignore it. As pooping is natural part of all real world animals its going to be in the game. Fantasy animals feature different kinds of beings which allows for interesting and funny questions, does this animal poop? Non naturalistic animals might have their unique trash items that they leave behind instead of generic poops.
Poop mechanic was experimented with slimes and now most of the animals have some kind of poop/trash object that they will leave behind occasionally. Too dirty enclosures make the animals unhappy so workers need to clean up the mess regularly.
