Mickey and Megan were making paintings of the scenery on the farm yesterday. Painting sure can get messy! Since it has just stopped raining, Mickey decides to look for some more fun things on the farm to paint. Then he sees his first ever rainbow! He thinks someone made a mess in the sky after spilling all their paint. But Rhiannon the Rainbow explains that rainbows like her are rare and special and usually only come out after it rains.
