Once upon a time in a sunny ocean, there was a clever fish named Fin. Fin was always curious and loved exploring the underwater world.

One day, Fin discovered a treasure chest hidden among the coral reefs. He quickly realized that the chest was locked with a mysterious code. 'I must solve the puzzle to see what's inside,' thought Fin.

With his sharp memory, Fin recalled a rhyme he had heard from an old turtle. 'Red, blue, yellow, green, unlock the treasure you've never seen.' He swam around, searching for colorful objects in the ocean.

Fin found a red seashell, a blue starfish, a yellow sea anemone, and a green sea turtle. He arranged them in the correct order and poof! The treasure chest popped open.

Inside the chest, there were shiny pearls and sparkling gems. 'Wow! These are the most beautiful treasures I've ever seen,' exclaimed Fin.

But instead of keeping the treasures for himself, Fin had an idea. He decided to share the treasures with his fish friends who didn't have shiny scales like him.

Fin distributed the pearls and gems among his friends. They were overjoyed and thanked Fin for his kindness. From that day on, every fish in the ocean knew about the clever and generous fish named Fin.
