Paint the inside and outside of a styrofoam half ball in your chosen Story Bot’s color.
Cut two circles out of a sheet of white craft foam and using a black sharpie, draw pupils for the eyes. Cut two rectangles from clear plastic (like an empty water bottle) and two rectangles from a sheet of colored craft foam for the eyebrows.
Using hot glue, attach the eyes to the styrofoam half ball. Also attach the eyebrows to the clear rectangles and those rectangles to the eyes.
Finish it off by attached an elastic chin strap across the inside of the head with hot glue.
