I can't believe someone actually noticed those three pixels. You can't even spot it on Tails unless he's running.
Sonic Retro. The same community who bitched about one pixel being off when it came to remastering art for Sonic 2 HD. We pay attention to details. Some of us are anal retentive and some of us just notice something off to begin with. Three pixels sure, but it was a very cleverly hidden surprise for those who went to the extra trouble of examining the game. When the guy tells me he wants me to think, I'll look at everything.
