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 live in the Twisted Suites and hold The Spectral Catch's elevator button. It is not specified in the game which ghost each name applies to.

Appearance
Nikki, Lindsey, and Ginny are small purple female ghosts with blonde hair, gleaming white eyes and long eyelashes. They wear dark purple tuxedos, capes, top hats and white gloves. The first one has a ponytail, the second one has a pair of pigtails and the third one has a pair of shorter pigtails.

History
The triplets 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 triplets appear and cause curtains to appear; when they fall, the room has transformed into an inter-dimensional space. They then give showman poses before retreating into their hats and attacking Luigi and 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 Strobulb 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, though she will eventually escape back into the hat after some time; Luigi can easily dodge this by watching for the triplets to raise their wands as it emits a sparkling blue trail.

After one of the triplets is sucked in, the remaining two will repeat their attack pattern, placing a bomb under their captured triplet's hat as a trap. If Luigi pulls out on the line of scarves linked to the hat with the bomb inside, he will take 20 damage as the remaining triplets laugh at his misfortune before restarting their attack. When all but one of the triplets are captured, she 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.

The triplets 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 third and final triplet to be captured makes a more prolonged attempt, but to no avail, allowing Luigi to claim The Spectral Catch's elevator button.

Trivia

 * In Japanese, Chinese, Korean, English, French, 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 sound being the same in Japanese.
