Kinda, I came up with the idea a while ago when I wanted to make a Knuckles' Chaotix paraody mini-series, but I couldn't find all the backgrounds I needed, and I doubt I could've followed through. But yeah, the comments on that blog reminded me of this joke, so I made the comic as a stand-alone piece.
