for Puddle by Hyewon Yum
One rainy day, a little boy is upset because he can't go out and play. His mom comes up with a way to keep him entertained--by drawing a picture of herself and him going outside, playing in the rain, and splashing in a giant puddle. They have so much fun drawing themselves that they decide to venture out and make the most of the rainy weather.
