Behind the Waterfall
Behind the waterfall after transforming into 2D Mario in Cascade Kingdom.
How to Get
- Enter the pipe just before the Madame Broode Boss Fight (you need to break the wall using the Big Chomp there).
- You will transform into 2D Mario. Make your way up while destroying the blocks. When you reach the third level of the area, there will be a wall on the left with a hidden block above. Jump up to hit and reveal it.
- Use the invisible block to get to the area on the left. The Power Moon will be there.
