Coco the chipmunk loves sweet potatoes, and loves sharing them with her friends, often as a way of cheering them up. When Coco is sick in bed, all the friends she helped come to help her as well.

An author's note explains that "In Korea, we often greet family, friends, or even people we've just met by asking, 'Have you eaten?' It's not simply asking if someone ate a meal. It's the same thing as asking, 'How are you?'" It was widely used as a greeting after WWII and the Korean War "to show concern about another person" at a time when many didn't have enough to eat.

Back matter includes "Coco's Cooking Class," a recipe for Korean-style sweet potatoes.
