Once in a magical forest, there lived a beautiful unicorn named Sparkle. Sparkle had a shimmering white coat and a horn that sparkled in the sunlight. One day, Sparkle discovered that the rainbow in the sky had disappeared. She knew she had to find it bring back the colors to the forest.

Sparkle set out on her journey, trotting through the forest and asking the animals if they had seen the rainbow. The wise old owl told her that the rainbow had been taken by a mischievous gnome who lived deep in the woods. Determined to find the rainbow, Sparkle followed the owl's directions and soon reached the gnome's lair.

The gnome was guarding the rainbow, using its colors to paint his house. Sparkle knew she had to come up with a clever plan to get the rainbow back. She used her magic to create a distraction, allowing her to sneak past the gnome and grab the rainbow.

With the rainbow in her possession, Sparkle raced back to the forest. As soon as she placed the rainbow back in the sky, the colors spread across the land, filling the forest with light and joy. The animals cheered and thanked Sparkle for her bravery and kindness.

From that day on, the magical unicorn Sparkle was known as the hero of the forest, and the rainbow shone brighter than ever before, reminding everyone of the power of friendship and courage.
