Found in the house of a ghost cap in Cap Kingdom.
How to Get
- Head to the Central Plaza. On the upper-left corner of the area (opposite the double top-hat house) is a house with a Power Moon inside. The entrance is blocked by a ghost cap.
- Capture a Paragoomba on the bridge that goes to the Top-Hat Tower and flow to the house. The ghost cap will run away, allowing you to get the Power Moon.
