Have the model files for the LEGO Sonic head piece been released in LDD or LDraw parts library? I am referring to the "LEGO Dimensions" video game Sonic head piece. I can't seem to find the name of the model, assuming it even exists in these libraries. I've been looking for it everywhere.

I have the latest version of LDD and after a thorough examination of the available head pieces, I can report that the Sonic mold has not been added to the parts library. If anyone else here has the latest LDraw parts library, they will be able to answer the other half of this question. 

Here is a shot of all the non-standard head molds:
