Far out in the deep blue sea lives the most spectacular creature in the entire ocean. He is called the Rainbow Fish, and his scales are a breathtaking array of shimmering silver, blue, green, and purple. He is undeniably beautiful, but he is also incredibly vain. When a small blue fish asks for just one tiny, glittering scale, Rainbow Fish proudly refuses and turns away. Soon, the other fish stop playing with him, leaving him completely alone with his unshared beauty. Desperate for companionship, he seeks advice from the wise octopus. He learns a difficult but important lesson: true happiness does not come from admiring yourself, but from sharing what you have. By giving away his prized scales, he discovers the joy of friendship and the real meaning of being beautiful on the inside.
