Ha ha, I do know some obscure game stuff... but then again, remember that I had no idea there was a Cocobot! I had a Master System when I was younger and fondly recall Psycho Fox and always wondered why there was never a sequel. Even after I learned about Decap Attack and Magical Hat no Buttobi Tabo, I missed the characters from the original. lol, when I was just a wee lad, I even wrote Sega and told them to make Psycho Fox, Tails' long lost brother.
The ol' Evil Clown, eh? Would I be incorrect in guessing that this would be your Clown Contest entry? I like how you used the best of its various incarnations (like the older sprite's horns, but the newer ones' color interpretations).
