In World 1-3, Mario finds himself on a steep mountaintop. He is tasked to scale down the mountainous path, dodging Piranha Plants and Koopa Troopas. On the way down, he finds a bonus box filled with coins. After the short way down, Mario finds the Checkpoint of the level. After the checkpoint, Mario rids a large switch platform on wires above a large chasm. Crossing the chasms, Mario must then fall from the tall heights to a small platform. From there, Mario rides another platform to the Flagpole near a waterfall in the background.
- Star Medal 1: Use the binoculars and seek on the Toad. He'll throw a Star Medal and it'll stop above the note block.
- Star Medal 2: Take the Magic Note Block and once in the cloud level, Mario or Luigi will find the second Star Medal at the end of the path.
- Star Medal 3: The third Star Medal can be found somewhere in the Cloud platform section. It can be easy to find.
