"Is the sky grumpy at me?" Thunderstorms can be quite scary for young children. For Anna, the storms not only frighten her, they interrupt her favorite activity - playing outside with her toys. One day, she is playing outside with her mother when a thunderstorm approaches. She grows quite apprehensive at the sight of the lightning and the sound of the thunder and dubs the sky "grumpy." After the storm passes, it leaves a large and wonderful puddle by her house, and with the help of her mother, Anna learns to sort out her fears and anxieties regarding storms and has some spectacular adventures in The Grumpy Puddle.
