Trapper

Trappers are orange ghosts in Luigi's Mansion 3. They have two blue tongues, both of which need to be sucked up by Luigi and Gooigi to defeat them. They have 0 HP.

Behavior
Trappers wait in front of doors while invisible. If Luigi comes near them, they will reveal themselves and grab him with one of their tongues. Trappers can also be found against the wall in narrow hallways, and will grab Luigi when he passes by them. To prevent Luigi from taking damage, the player must call out Gooigi and have him grab the ghost's other tongue to make it let go. Trappers are the most rarely appearing of the types of ghosts in the game's story mode.
