Caterpillar is technically not any older than Butterfly.
She believes she is the guardian of a mysterious stone, but can’t remember why.
Caterpillar will go out of her way to keep a promise. Vaguely aware that she is incredibly vulnerable to danger, she does everything—everything—as if it may be her last moment alive.
Caterpillar has a cautious fascination with the Sun. She is afraid of it, but she also waits and watches for it to rise (from behind a leaf) in the early morning. She will turn and watch again, no matter what she’s doing, when it’s time for it to set.
