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, when Moko sees a shooting star zip right over the mountaintops, he wonders whether there isn't someone over there making stars. He goes to the mountain and finds a woman tending a huge fire. Thousands of sparks fly out of the fire and rise, twinkling, into the sky. He thinks he has discovered the secret of the star sprinkler.
