Peter, The Snowy Day's protagonist, wakes up to the season’s first snowfall. In his bright red snowsuit, he goes outside and makes footprints and trails through the snow. Peter is too young to join a snowball fight with older kids, so he makes a snowman and snow angels and slides down a hill. He returns home with a snowball stashed in his pocket. Before he goes to bed, Peter is sad to discover the snowball has melted. The next day, he wakes up to tons more falling snow. With a friend, he ventures outside again.
