I think it would be cool if the bathroom area was a horror/backrooms themed area. If you don't know what I'm talking about look at the map on top of the lectern.

Maybe they could add a new bug or 2. I think one bug found there needs to be a spider as strong as the wolf spider but not the wolf spider as personally I have never seen one in a bathroom like that. The other bug needs to be the Phorid (Humpbacked) Fly as they love being around places like that. The would be a territorial bug, like the Mantis, and only attack the player if you get too close to the toilet bowls, or wherever they are. They can be found in groups of 5 and attack as a group but one a time. Their attacks could be flying into you landing and hitting you with their feet or spitting their digestive fluids at you. The acid will act like Tang however it will do more damage and is not an area it only works if it hits you.
