Sadie has a bone connected to the eyes. It actually has three parts. One for "Eyes", another for "Right Eye" another for the "Left Eye".  It works spectacularly! I don't know how it's rigged, but if you have her, take a look at it.  I got her back when I had money, and never regretted it.  THOSE eyes are a real joy to pose.  Something I can NOT say about MOST poser figures.  Who ever came up with it was a freaking genius!
