There are a variety of ways you could draw eyes. But, as a matter of priorities, I would first focus in laying down a trail (or sequence of turtles) indicating the turtle's path.
You could use a texture (internal image) to put eyes on your turtle. You could do something like a soccer ball with only one black face. (Clipping would mean the part inside the turtle wouldn't be seen.) You could do movement by moving the eye geometry or you could do movement with a sequence of images that you index through. Etc. But it's good to learn to walk before you run...
