When my kids were growing up, I hollowed-out and carved a scary head from a cantaloupe, using grapes for eyes and to fill the empty head. Since this was near Halloween, the kids were at first shocked, then delighted to open the refrigerator to find breakfast, and instead to find a melon-head staring out at them. My oldest daughter has since graduated from college and has been working in industry the past 5 years, yet she remembered still the fruit head, so she asked me to carve some fruit skulls for a work Halloween party. Attached are the results. The honeydew mellow was nearly perfectly round, so Charlie Brown seemed a natural selection.
