I could have sworn I saw this somewhere before, but whatever. This is a really cool picture because of how dark it turns the Mario world. It's not just something that's dark for the sake of being dark. The scenario actually somewhat fits the tone of the game. It reminds me of "Marvel Zombies". Yeah, they should stop with those.
It's weird how Yoshi has no arms in this. You would think it would be harder for him to kill Mario. Or maybe it was the Thwomp that killed him and Yoshi's eating his body. I noticed there are little penises in the corner of the picture. Classy.
