- Inflicts insanity when visited
- Wins if all players are insane
- Insane players can not visit Cthulhu and their vote does not count
- Insane players do not know they are insane, in their perspective they chat and vote normally
- In the perspective of other players, though, their messages are replaced with random words and whenever they vote their vote shows up on a random player.
- For example if thulu'd says "someone help me" it might be replaced by something such as "Apples sombrero laboratory"
