When a boy helps free a dolphin tangled in a discarded fishing net, they develop an unexpected friendship.

"Once there was a boy who lived by the sea. He loved the sea and he swam in it every day he could ... which was most days. He was a very good swimmer.

One day, the boy was swimming as usual when he noticed some splashing further out in the water. He decided to take a closer look."

This title is also available in the Māori language translation Te Tamaiti me te Aihe.
