Ruins of Desert (さばくのいせき), as it is named in Encyclopedia MOTHER, are a series of caves in EarthBound Beginnings, found in the eastern portion of the Yucca Desert. The ruins are inhabited by monkeys, and all but one of them try to trick Ninten and his friends into getting lost. It is an optional area that can only be reached after R•7037 is destroyed, which is visited for additional goodies and another warp point for Magicant.
