Game Specific Model Ripping Guides

[Tiberious]

I got it, but Sonic's Eyes are close...

The game uses multiple instances of Sonic's eyes and muzzle, as (my guess anyway) morph targets.

When you import the PSK or MD5MESH, you should be able to select each object by itself and move them off to the sides (if you use Blender and hold Ctrl while dragging, it will move in larger chunks while snapping to those points).

When you find the eyes/muzzle combination you're looking for, you can move them back to the main model.
