Is there any Sonic _______ Character? (Click to find out what!!!)

You see I have an account on a Site called "CDE(Cartoon Doll Emporium).com",
So I'm playing this Scavenger Hunt, It's showing a pic of Sonic, But the Clue writting sais "This amazing vampire doll is holding the next clue. Find her before she disappears into the night." so who is this Vampire Sonic character? Help please! Nobody can figure this out :( So can't I...SO HELP!

I tried Sonic, Nothing happans, I tried Rouge but there's no doll of her, So who is this Vampire Character?
Or is CDE just having trobles with the pic and it's showing pics of other clues?
HELP!
Oh by the way, I tried ALL the Vampire Dolls...it'l like been 2 months since I started searching...
