Ive spent quite a bit of time working on the details and like the others gave him a different look. My goal was to blend in his echidna counterpart while maintaining a conservative look so he wont look unrecognizable.
I don't usually do stuff like this, so I decided to make something unique. Essentially this is a (hopefully) full sprite sheet for Sonic to serve as a replacement for Carbunkle/Has Bean and Arle in Mean Bean Machine (I always thought it was odd how he didn't appear in that game to begin with).
This was just a bit of fun I decided to finish off and upload, I don't know the proceedures for making game sprites so I have no idea if this could actually work in a game, I'd fully commend anyone who wanted to though, especially since MBM hacking is near null right now.
UPDATE: Converted to PNG format since TIFF format images get compressed when uploaded.
