Several enemies from Wario Land 2 -- specifically, all the ones that either have official artwork or appear in the matching minigame -- touched up, recolored, and shaded to give them a 16-bit appearance. Enemies with official artwork have been modified to more closely resemble it.
Feel free to use this for whatever you want, no credit required as long as you credit Nintendo for making this awesome game in the first place.
