Study the images to recreate these food arrangments yourself. If you eat Japanese food, you'll enjoy making the Kaitou St. Tail design. What a cute bentou (boxed lunch) it would make! I didn't find instructions, but I'd use fish cake or boiled egg (without the yolk) for her face and meat or ginger for her hair. Her hair ribbon is likely seaweed. Kero-chan is done with orange sherbert or ice cream, small Ritz crackers, and any sort of chocolate morsels, such as mini chocolate chips.
