Nikki, Lindsey, & Ginny

Nikki, Lindsey, & Ginny are a trio of magician ghosts who collectively serve as the twelfth boss in Luigi's Mansion 3. They haunt and seem to live in the Twisted Suites and guard the twelfth floor's elevator button. It is not specified in the game which ghost each name applies to.

Appearance
Nikki, Lindsey, and Ginny are purple female ghosts with blonde hair, gleaming white eyes, and long eyelashes. They wear dark purple tuxedos, capes, top hats, and white gloves. One of them has a single pony tail, another has two long pony tails, and the third one has two short pony tails.

History
The trio are first seen immediately after Luigi exits the elevator, to which they taunt him before moving out of the room. They appear in various rooms and continue to scare Luigi around the floor until he makes it to the Wardrobe, where they use their magic to scramble the doors, causing them to lead to different rooms from the ones intended.

When Luigi returns to the Stage, the trio appear and cause curtains to appear; when they fall, it shows an inter-dimensional space. They then give showman poses before ducking into their hats and attacking Luigi, and then spin around him before laughing as they disappear. The boss battle then begins.

Battle
After taunting Luigi with a synchronized bow, they cast an illusion on the stage. Nikki, Lindsey, and Ginny will then duck into their hats and begin spinning. Each hat launches a playing card projectile at Luigi, who can dodge it by moving out of the way or catching it in a Burst. The hats will then begin orbiting the stage, launching a few more cards before glowing red around their rims and attempting to attack at close range. When the trio is close enough, Luigi must catch them in a Burst to flip them over and reveal lines of scarves; by pulling on a line, he can force out one of the girls to stun her with his Flashlight and suck her into the Poltergust G-00. If Luigi misses a hat, it will attack him with an unavoidable card, causing him to trip and let all the immobilized hats escape to resume their orbit. When one of the girls is forced out of her hat, her only attack is a swipe with her wand; Luigi can easily dodge this by watching for Nikki, Lindsey, or Ginny to raise her wand as it emits a sparkling blue trail.

After one ghost is sucked in, the remaining girls will repeat their attack pattern, placing a bomb under their missing member's hat as a trap. If Luigi pulls out a bomb instead of a ghost, he will take 20 damage and the ghosts will laugh at him before restarting their attack. When a second member of the trio is captured, the remaining one will summon two decoy hats rigged with bombs; when they begin orbiting Luigi, the lights will periodically flicker to make it even harder to track the correct hat.

All three ghosts have the same defeat animation: they struggle furiously to escape the grasp of the Poltergust G-00, only to ultimately fail and be sucked in. The final ghost to be captured makes a more prolonged attempt, but fails all the same, allowing Luigi to claim the 12F elevator button.

Trivia

 * In Japanese, Chinese, Korean, English, French, European Spanish, and Dutch, the magician trio's names begin with N, L, and G. When put together, their initials reference Next Level Games, the developer of Luigi's Mansion 3. The Japanese version however is more subtle due to the L/R letter being the same in Japanese.
