Two happy children play in their backyard during a rainy day. The brother and sister explore how animals hide from, react to, and play in the rain, and invent many ways to splash about while enjoying a rainy day. After warming up and drying out at home, the siblings go to bed hoping for a sunny day in the morning. This beautifully illustrated book from Caldecott winner Peter Spier has no words and invites young readers to tell the tale from the pictures on each page.
