On a cloudy day, Miffy and Barbara Bear go out to look for some coloured leaves. When it starts to rain, Barbara walks Miffy home under her big umbrella. From the coloured leaves they have collected they make some beautiful rain clothes to wear! Grandpa and Grandma Bunny take Miffy to the beach. They remember making sandcastles when they were young, so that is what Miffy decides to do! She meets Melanie, and together they play with a ball. They won’t get lost, because the sandcastle marks the place where the family is. But then the tide comes in, and soon the sandcastle has been washed away.
