Inside the backrooms, at the M.E.G base.. You see a.. 17 feet tall Partypooper that seems to have bandages on it's left eye, and right arm, and their upper torso. They seem to uh.. Sorta have a tail of some sort and a pretty nice pair of claws on it's.. I think left hand. (Sorry, I'm not good at left or rights) though, they don't seem to notice you.. Yet.
