Toy Island is also doing a run of keychains under the "Sonic X" name. They are claiming that this is "Cheese the Chao" but that is a LIE.

See, there's no bow tie. This is actually a re-do of the PVC chao that came with TI's inital release of Sonic Adventure 1 figures. It was with their "Wind up Tails". They just put a keychain lead on it, and are claiming it's Cheese to fit with Sonic X. Bad form, Toy Island!

You can see that Sonic Knuckles Tails and Big (why not Amy? Because she was never on their first line.) should also be in Key-Chain form.
