Elite Octogoombas are a type of Octogoombas that first appeared in Luigi's Mansion 5: Curse of the Mansion. They bear a strong resemblance to their blue cousins, but instead of being blue, they are green, and they have two antennae rather than one. Elite Octogoombas' attacks are much similar to those of an Octogoomba, but they are able to shoot two rocks rapidly instead of one. They appear in the Honeylife Mansion and the Bowling Boulder Mansion.
