Tosarena Ruins

Walkthrough: Immediately after entering the ruins off Tosarena, Mario and Cappy will be attacked by more Yellow Goombas. After defeating them, take notice of the Robot Binoculars to your left. You can use Cappy to capture it and use its Bird-Eye View of the entire area; you can see the upcoming tower, the pyramid beyond it, and the island off to the left that is surrounded by a large chasm.

After doing so, enter the ruins and go right until you reach a rather small path. Here, Bullet Bills will be shot at Mario, and beyond them will be moving platforms that can take you further into the ruins. Quicksand will be below the platforms, so make sure not to fall to your doom. If you're having trouble dodging the Bullet Bills why trying not to fall off the platforms, try taking control of one with Cappy to help you reach the other side and and continue onward.

Once on the other side of the platforms, there will be even more Bullet Bills, as well as a number of Goombas. Use the Goombas and platforms provided to avoid the Bullet Bills. Try to get to the right of the launcher, and then ground-pound on the flower to open its petal. This will allow Mario to super bounce to the platform way above, but before you do, don't forget to get the next Power Moon in the bottom corner of this area.
