Kinky

Kinky (Japanese: 金ぞ Kinzo) is a type of ghost from Pac-Man Arrangement.  They are naturally gold-colored (his Japanese alias, Kinzo, roughly translates to "gold"), but are always vulnerable when Pac-Man is on the maze. Because of this, a Kinky cannot harm Pac-Man directly. Their only defense is combining with another ghost. The ghost he is chasing after becomes significantly slowed down until a Kinky catches that ghost.
