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, on that night the tide was low and the boat had been beached. Moko and Alarick were playing percussion and flute to pass the time. Suddenly, it was as if their music was being accompanied by a strange singing. They decided to investigate the source of this strange new sound. Walking along a hilly path in the forest, they were surrounded by hundreds of tall rocks that stood like humans in the dusk. A gust of wind blew and they could once again hear the bizarre song. Frightened at first, Moko and Alarick decided that the rocks were singing as a choir and the joined them with their instruments. When the wind fell, they regained their boat, happy to have participated in the symphony of the singing stones who were probably lonely and wanted to attract visitors.
