Peel and cut bananas in half.
Insert popsicle stick into each banana half and lay on a baking sheet lined with parchment paper.
One at a time add yogurt to banana. Twirling in a bowl works, but I also find using the back of a spoon to scoop the yogurt on and then smooth it out.
Add chocolate chip eyes.
Freeze.
After they are frozen, you can add them to a glass dish lined with parchment paper in between layers.
