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, Moko learns about water tables and how streams develop. During the dry season, the river level drops and the remaining water turns to mud. He can't swim or drink the water. A man with a strange stick points the stick to the ground, and when Moko digs down there, water gushes out! Moko learns that even if no rain falls, Mother Earth could still be generous if you know the right way to ask her.
