Frank stared at her. But you throw Ding Dongs at monsters.Iris looked horrified. Oh, they're not Ding Dongs.She rummaged under the counter and brought out a package of chocolate covered cakes that looked exactly like Ding Dongs. These are gluten-free, no-sugar-added, vitamin-enriched, soy-free, goat-milk-and-seaweed-based cupcake simulations.All natural! Fleecy chimed in.I stand corrected. Frank suddenly felt as queasy as Percy.
