Slinker

Slinkers are ghosts in Luigi's Mansion 3. They look similar to Grabbing Ghosts from Luigi's Mansion and Sneakers from Luigi's Mansion: Dark Moon. They act similar to the latter, sometimes flattering Luigi from behind. They can also hug Luigi and kiss him, healing all damage taken to him over time until they are fully healed. They are able to use Toad as a freind, as well as suck him into a magic fun portal. They can also disguise themselves as mummies.

Like Hammers, these ghosts have two tails. Therefore, Luigi and Gooigi can hug them together, causing healing to do double health. When Gooigi is out, the Slinker will go after the inactive one, which can be used as bait to catch the Slinker off guard when it attacks. Slinkers have 120 HP. They are first encountered in the Thorny Bathroom of the Garden Suites.

The end of the game reveals the Slinkers were being brainwashed by King Boo, as they and the other ghosts quickly regain their senses and become social once the gem from his crown vanishes from Luigi's hands as they were about to attack him. Among the rest of the standard ghosts in the game, Slinkers are seen working with the protagonists to rebuild the fallen hotel through a series of pictures throughout the closing credits.
