Blue Twirler

Blue Twirlers are slow normal ghosts Luigi encountered in the game Luigi's Mansion. They are one of the largest and most powerful non-portrait ghosts found in the mansion. Blue Twirlers have over-sized fists that they use to make ground pounds, or earthquakes, that spread three feet and take ten HP if they hit Luigi. They have thirty HP each, which can be whittled down by suction or elements.
