Every morning, she would join the dolphin and whale choir.

Her favorite song was about a boy who had a toy coin.

One day, the boy dropped his toy coin in the soil near the sea.

Joy saw the shiny coin and decided to fetch it for him.

She pointed her nose towards the coin and swam.

Joy managed to get the coin and started to swim back.

But a crab tried to spoil her plan.

Joy, however, was quick and got away from the crab.

When the boy saw Joy with his coin, he was filled with joy.

He thanked Joy and promised to be more careful with his toys.

And Joy, the koi, continued to sing her songs, her voice spreading joy in the sea.
