Could somebody please help me identify this Burger Mario?

Where is he from? Who drew him? What is this in reference to? What's its mission?

It really resembles an actual Paper Mario sprite to me, but kind-of reminds me of the TerminalMontage style.

If you just type "Burger Mario" into a search engine, you get a lot of irl meatspace burgers that are Super-Mario themed.

He's in my brain! Help me!
