Exclusive to: Don't Starve Together.
Cave Holes appear in the Ruins. There is a treasure in each Cave Hole. The items inside cannot be picked up directly; using The Lazy Forager or Wortox's teleport ability is the only way to pick them up. The Ruins can be regenerated by killing the Ancient Fuelweaver, so by defeating the boss repeatedly the player is able to farm the Cave Holes for loot.
