Using 2 forks, dip and roll chilled cookie balls, one at a time, into melted chocolate; tap off excess chocolate. Return to lined cookie sheet, and immediately press in eyeballs. Decorate using candies, nuts and sprinkles as desired, using photo as a guide. Repeat with remaining cookie balls. If chocolate has cooled too much, reheat. Refrigerate about 15 minutes or until chocolate is set. Store covered in refrigerator.
