In the depths of the ocean, a beautiful rainbow fish with shimmering scales lived happily among the coral reefs. One day, a mean shark with sharp teeth swam up to the rainbow fish and demanded, "Give me one of your shiny scales!" The rainbow fish was hesitant, but the shark's angry glare made him fearful.

Reluctantly, the rainbow fish plucked off one of his beautiful scales and handed it to the shark. The shark snatched it up and swam away, leaving the rainbow fish feeling sad and bare. "Now I'm not as special anymore," he thought, his black eyes filled with disappointment.

Suddenly, a mermaid with brown skin and black hair appeared. "Why do you look so down, little rainbow fish?" she asked in a soothing voice. The rainbow fish explained what had happened, and the mermaid nodded in understanding. "I have an idea that might help," she said, and swam off.

When the mermaid returned, she was carrying a white t-shirt. "Here, put this on," she said, handing it to the rainbow fish. The rainbow fish was confused, but he trusted the mermaid. As soon as he put on the t-shirt, his scales began to shimmer and shine even brighter than before!

"Now you are even more special than you were before," the mermaid said with a smile. The rainbow fish swam around happily, his shiny scales sparkling in the sunlight that filtered down through the ocean waves. From that day on, he never again gave away his precious scales, for he had found a way to keep his unique beauty forever.
