This is a short story that tells of an adventure experienced by the Coconut family, a family that loves fun, playing, dancing, and singing, living peacefully on a small island in the middle of the ocean. One day, while they were playing with a ball near the seashore, the ball fell into the sea and drifted away until it disappeared from their sight. They decided to go in search of the ball and swam in the ocean waters after it.

Suddenly, they found themselves in front of a very large city. They were afraid of this city at first, but they quickly got to know a family called the Banana family, who welcomed them and helped them return to their island safely.
