However, the Nomadimouse king of this desert was attacked and killed in his palace in Dry Dry Ruins. The bandits later built Dry Dry Outpost. Soon the desert would become a part of the Mushroom Kingdom. Many years later, Bowser had his minion Tutankoopa hide in Dry Dry Ruins. Then Mario came and defeated him saving the Star Spirit.
