Sneaker

Template:Species-infobox Sneakers are dark-purple ghosts that appear in Luigi's Mansion: Dark Moon. They usually appear in a group of three or with two or three Greenies. They have 25 HP. In mission D-2: Hit Rock Bottom, 3 Boos are showed to imprision a Sneaker, a Greenie and a Slammer into red crystals, which transforms them into their Strong forms.

Sneaker will sneak (as the name says) behind Luigi and scare him, disrupting him while he is sucking ghosts with the Poltergust 5000. They can attack by strangling Luigi, causing him to lose HP. Although a Sneaker is normally invisible until it goes behind Luigi, the player can use the Dark-Light to find him while he is sneaking.

These ghosts are swift and cunning. They love to turn invisible an sneak up behind the targets of their pranks, so use the Dark-Light Device to catch them in the act!
