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 wonders why the moon changes shape so often. Sometimes, when he sees the moon rising in the distance like the sun, he thinks that by walking towards the horizon he could get closer and find out more. That way he could even ask the moon itself. During his long walk towards the ever-receding horizon, Moko watches the moon constantly changing shape. Sometimes it's a crescent like a smile, sometimes a disc of light; sometimes it's white, sometimes yellowish. It travels across the sky but you can't see it moving. One night, Moko decides to watch the moon perform its lovely dance among the stars. He figures he'll never reach the horizon, and in fact maybe the moon just wants to put on a show, to be watched more often.
