The Partygoers are tall, bipedal creatures with rough and leathery skin, typically tinted a dull yellow. They have no other functional features, with the exception of a cartoonish smile drawn onto their "face" with a substance resembling human blood. The Partygoers are highly intelligent, reportedly being spotted operating complex machinery and effortlessly traversing the Backrooms in search for prey. Most do not venture alone; rather, they tend to hunt in groups.
