Under Cheese Rocks

Walkthrough: After defeating another Broodal, look behind you and off to the left to find the hidden blocks on top of a blue platform. This will let you get to the roof of the previous area, which happens to hold both Purple Coins and a Power Moon. After obtaining them, head back to the arena and cross the bridge to head up the path into what is called Perono Plaza. By talking to on of the locals after you do, you will learn of a creature called Cookatiel having taken over the stew pot on top of the volcano.

Before heading that way in order to stop him, break the crates next to the Crazy Cap Store and the Slots Buildings to find two Power Moons. You can also find another Power Moon by tossing the golden turnip in the top corner of the plaza and throwing it in the nearby pot. From there, head east of the plaza in order to capture another Lava Bubble and nab more Purple Coins under the platform. After doing so, head across and up the given bursts of lava and then onto the platform to the left. Avoiding the number of Goombas, cross over to the following area.

In this area will be many Hammer Bros, ones you can capture using Cappy in order to destroy the giant blocks of cheese around them. The lever to open the nearby barrier containing the Power Moon is somewhere in the this area, so defeat all the Hammer Bros and then head up the cheesy steps to find the level and some more Purple Coins. Exit the Hammer Bros you have been using, and then use Cappy to hit the switch so you can nab the next Power Moon.
