High above the little village of Willowbrook was a place called Rainbow Hill.

Every morning, when the sun climbed above the clouds, a young unicorn named Lumi raced to the very top.

Lumi had a special job. This little unicorn helped paint the morning rainbow.

That flowing mane shimmered red, orange, yellow, green, blue and purple. And when Lumi shook that rainbow tail, colours danced across the sky.
