Once upon a time, in a world where every day was filled with sunshine and laughter, there lived two little clouds named Whisp and Fluff. They were the happiest of friends, always floating side by side, spreading joy wherever they went. One day, after a heavy rainstorm, Whisp and Fluff decided to create something special. They worked together to form a beautiful rainbow that arched high into the sky. The colors were so vibrant and bright that they lit up the entire town below. As the townspeople looked up, they saw not just a rainbow, but a message of hope and happiness. The words 'Smile under the rainbow' appeared in playful, colorful letters above the rainbow, reminding everyone to find joy even after the storm.
