This is Sableye, the Darkness Pokemon.

Its diet mostly consists of gemstones.

Sableye's Oden

I'm so hungry...

Oden

Step right up! Get a steaming hot bowl of Sableye's signature oden!

Ooh, that sounds good.

I dug up these gems myself!

Just ¥1,000,000 a scoop!

That's too expensive! And I can't even eat those!
