The Traitor is the player who picks up the Golden Crowbar, activating the Evil Ending. You must have full Energy to pick up the Golden Crowbar and there needs to be at least two or more players alive, or you cannot take it. After the Evil Ending, they will be wearing the “comedy” mask, like the ones the Villains are wearing. It is intended to make people feel frightened, but most of the time, the mask glitches out and ends up not producing the effect intended.
After the Evil Ending, the Traitor can dash around and explore like the other players. However, the Golden Crowbar is placed in the player's hand and the comedy mask is on their face, revealing their evilness.
