Miffy learns to play the recorder. As music is more fun to play with other people, she asks her friends to join in. Aggie brings her accordion, Poppy Pig brings her double bass and Grunty plays the piano. Together they sound wonderful! It is a rainy day, and Miffy is a little bored. She tries different things to keep her busy; she does the dishes, sweeps the floor, draws pictures, reads a book and listens to music. Meanwhile, outside the rain has turned to snow! Now she can go out again, and discovers how wonderful it is to play with her friends in a snowy white world.
