People think there are 4 SMW Luigi's, but there is actually another SMW Luigi from the MS DOS version of Mario's Early Years. However, while it is an edited SMW Mario sprite it isn't actually in SMW style. So I recreated the sprite and reshaded it with colours from the SMW palette. The sprites are also available in the original palette.
Not every animation from SMW is on this sheet.
