Duncan’s crayons are at it again, escaping their box to explore his room and have adventures. Each crayon finds something new to do—Red drives a firetruck, Blue helps a doll, and Esteban tames a teddy bear—sharing exciting stories of the friends and adventures they encounter.
One day it rains hearts, and Cornelia Augusta catches them. Each heart is special in its own way, and Cornelia Augusta knows exactly who to send them to.
