Golden Goob

Gold Goobs are rare, golden ghosts in Luigi's Mansion 3. They are rare, golden versions of Goobs, similar to Gold Greenies from Luigi's Mansion: Dark Moon. They are occasionally found throughout The Last Resort and drop treasure if defeated. If Luigi finds one, it will panic and run around the room, trying to escape. If Luigi does not capture it in time, it will escape and cannot be captured anymore.

Gem Goobs, another rare variety of Goobs, also appear throughout the game, and, similarly to Gold Goobs, they will drop treasures if defeated.
