Nikki, Lindsey, & Ginny

Nikki, Lindsey & Ginny are collectively the twelfth boss encountered in Luigi's Mansion 3, who haunt the Twisted Suites and guard the twelfth floor elevator button.

Appearance
The trio are first seen immediately after Luigi exits the elevator, to which they taunt him before moving out of the room. They appear on various rooms and continue to scare Luigi around the floor until he makes it to the main stage, to which they apparate and give a showman pose before ducking into their hats and attacking Luigi, and then spin around him before laughing as they disappear. They then teleport Luigi into another dimension via curtains.

Battle
The three ghosts, after posing, will duck into their hats, spit cards at Luigi, and then orbit him and continue spitting cards before attempting to attack at close range. When the trio is close enough, Luigi must Burst the area to immobilize them, then pull out one of the ghosts to suck her into the Poltergust G-00. The remaining members of the trio will repeat their attack pattern, except that they will place another hat with a bomb inside that damages Luigi if he attempts to pull it out later. If Luigi guesses the wrong hat, he will take 20 damage from the bomb that he pulls, the remaining ghost will then laugh at luigi and restart their attack. Additionally, once Luigi sucks in the second ghost, the remaining ghost will summon two decoy hats, and will even momentarily turn off the lights while orbiting Luigi to throw off the player's attention to the correct hat.

All three ghosts have the same "defeated" animation: they struggle furiously to escape the grasp of the Poltergust G-00, but ultimately fail and are sucked in.
