Mario Slug 3 [Fan Art/Sprite Edit]

Saw this via TinyCartridge just now.

A member of Pixiv called Mr.Rabbit has created a set of Mario Bros x Metal Slug 3 fan arts/sprite edits, which are pretty cool, would have been even better if someone made a fan game of it though. xD

I'm not quite sure how to navigate Pixiv properly, but check out more pics of this on TinyCartridge and on Mr.Rabbit's Pixiv page.
