The root bone is the main bone needed in order to create an animation.
 
The eye bone is the bone that you will connect the eye to.  No movement in needed for the eye.
 
The upper and lower eyelid bones must be separate in order to create the movement of an eye blinking.  The separate upper and lower eyelid objects are attached to these bones.  These bones do require a movement.  
 
* Note step by step instructions of this skeleton and sequence at not shown at the anim8tor website. To get help you can refer to http://www.anim8or.com/main/index.html.
 
Skeleton
In the sequence I picked to change the eye by frames of 5.  Therefore the eye would be half shut (as shown above) at 5, completely shut at 10, half open at 15, and finally open at 20.  Therefore it only takes 20 frames to make the eye open and close.
