User blog:Nitronack369/Unused Sonic Colors Badnik

So I was looking at Sonic Colors on the Models Resource when I discovered this: http://www.models-resource.com/wii/soniccolors/model/1095/ What appears to be an unused caterpillar/silk worm type badnik designed for the game. I've made several attempts to reconstruct the model, but it's currently over my head... I've not seen any mention of this badnik anywhere else on the internet, so does anybody know if this is used in-game, or if people have just glanced over it?
