I thought Queenie was Shadow... He's a more important character then Cosmo, I think. I didn't know she existed. I just had to look her up. XD It's a cute little plant-like girl! :P
I found an amazing picture of human Knuckles!

And this one is funny too. It's Team Sonic. Knuckles, Tails, and of course Sonic. :P http://th05.deviantart.net/fs8/300W/..._RyoKnight.png
