Mario uses these keys to open several locked doors to advance through the ruins and eventually get to the boss of the ruins named Tutankoopa. There are four Ruins Keys in total. The first one is found in the third room of the ruins. The secon key is found after pouring sand down into a room. The third is obtained after defeating the three Pokey Mummies that ambush you. And the forth and final key is two areas to the right of the Super Block
