A partygoer cannot talk. Once stumbling onto a wanderer they play a music box that makes the wanderer sleepy so they can't run. Then they transform the wanderer to another partygoer. They use their spiky, tooth filled hand to grapple on the wrist of a human. Then leaves. The process of turning into a partygoer is first you will skin will start to turn into a leather-ish material. Then you will loose memories. You will only think of fun. They will then draw a smiley face on their mask with blood.
