The Thing (That Goes Bump In The Night) is on the Villager team.
The Thing wakes up during the night phase and taps the shoulder of one of its neighbors. This lets that neighbor know that The Thing is sitting next to them.
If The Thing taps a player on the Villager team, they know that player is not a Werewolf. However, if The Thing taps a player on the Werewolf team, they know that player is not the Seer, Fortune Teller, or Apprentice (all roles which, if the Werewolf team figure out, can lead to them winning).
