Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, one day, it was very hot and the earth was very dry. Concerned that no rain was coming, Moko set out to find a man believed to be a wizard. The man told him to follow the path of the dunes, which would take him to a sea of sand. Moko walked for a long time. Suddenly a strange shape appeared in the distance. It resembled trees surrounding a small pond. But a few steps later he couldn't see it anymore. It had vanished into the immensity of the desert. Moko scanned the horizon again. He turned full circle and once again saw the pretty pond and surrounding trees. He walked toward it slowly, never taking his eyes off it, his heart pounding. This time he reached the edge of the small oasis, relaxed in its freshness and drank.
