Klepto Ruins is one of the places in Mario Party Advance. It is located in the Desert Area of Shroom City, but it can only be accessed by a pathway at the entrance to the Seaside Area. When the player decides to stop here, he or she meets Mr. E, who is confronting Klepto about a secret treasure. His quest, Treasure of Mystery!, involves opening Klepto's treasure chest by guessing the correct four-number combination. If the player gets it right, Mr. E will be fascinated, though he quickly loses interest and leaves, leaving Klepto to reward the player with the Map Maker Gaddget.
