Once upon a time, there was a fish named Fin who lived in a sea. Fin was a happy fish and had a big grin on his face all the time. One day, he met a crab named Bin who was always upset and had a frown on his chin. Fin asked Bin why he was always so unhappy and Bin replied that he had lost his lucky pin.
Fin decided to help Bin find his pin and they went on an adventure in the sea. They swam through a thin part of the sea and found a big bin where they thought the pin might be. To their surprise, they found a mermaid with beautiful skin who was singing a sad song. The mermaid explained that she had lost her voice and needed to find it to sing again.
Fin and Bin decided to help the mermaid find her voice and they went on another adventure together. They swam to the bottom of the sea and found a big box with a lock. Fin used his fin to pick the lock and inside the box, they found the mermaid's voice.
The mermaid was so happy and grateful, she sang a happy song and gave Fin and Bin a reward. She told them that their good deed would bring them good luck and happiness forever. From that day on, Bin had a big grin on his chin and Fin continued to be happy as ever. The end.
