Tree Root

The Tree Root is a "room" in Haunted Towers in Luigi's Mansion: Dark Moon. The tree root will be basically a linear root that, at the end, there will be a spiky ball hanging from a vine, if Luigi pulls down the vine, three Gold Spiders will appear. To advance into the Old Graveyard, use the Poltergust 5000 on the fake background, which will reveal another spiked ball. Pulling this one down will reveal a hidden elevator, which will take Luigi to the graveyard. The Tree Root is only visited in one mission.
