Nintendo has released their 20th piece of Super Mario Odyssey Hint Art. By now, you know how this works. The picture points to a place in a Super Mario Odyssey kingdom where buried treasure can be found. Once you’ve located the spot it is buried, you will need to perform a Ground Pound to dig it up. Nintendo’s official tweet containing the Hint Art can be seen down below.

Now this one’s pretty cryptic. One’s a boss in Steam Gardens, the other a boss in the Sand Kingdom. I really can’t tell what this hint is.
It’s probably on the path to a painting in sand kingdom that takes you to the forest kingdom. That grey block looks like stairs, maybe.
