Which of the following names is not a name for a ghost (monster) in Pac-Man?

The Ghosts in the Pac-Man franchise are primarily Blinky, Inky, Pinky and Clyde; they are the monsters chasing the player in the Pac-Man game. The enemies in Pac-Man are known variously as "ghosts," "goblins," and "monsters". Despite the seemingly random nature of the enemies, their movements are strictly deterministic, which players have used to their advantage. In an interview, creator Toru Iwatani stated that he had designed each enemy with its own distinct personality in order to keep the game from becoming impossibly difficult or boring to play.

Blinky is a red ghost who follows behind Pac-man. He is considered the leader of the ghosts. Pinky is a pink ghost who positions him/herself in front of Pac-man. Inky is a cyan ghost who has a fickle mood. He can be unpredictable. Sometimes he chases Pac-Man aggressively like Blinky. Lastly, Clyde ( pronounced as cli) is an orange ghost who acts stupid. He will chase after Pac-man in Blinky's manner. Today, Pac-Man is a pretty familiar character to most people around the world.
