Blue Twirler

Blue Twirlers are slow, normal ghosts that 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.

In a piece of pre-release footage, there are three Blue Twirler-like ghosts playing poker; though the cutscene itself isn't in the final game, they make a short cameo in the form of a screenshot in a texture in the scene when Mario is being turned back to normal.

A Blue Twirler occasionally appears in the Luigi's Mansion Court in the game Mario Power Tennis. They are also found in the Luigi's Mansion stadium in Mario Super Sluggers, where they stun fielders that run into the graves that the Blue Twirlers reside within.

Additionally, a Blue Twirler is exhibited among other members of the same species in a trophy that appears in both Super Smash Bros. Brawl and Super Smash Bros. for Wii U. In each one of them, the trophy can be unlocked at random.

Slammers from Luigi's Mansion: Dark Moon behave similarly.
