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 tells himself that it is time to leave Mei-Lei's land and he gets his raft ready. A man tells him that he must take the route of the great plains to continue his journey. As he walks a great gust of wind makes him fall and drop his precious stone. Seeing it on the ground, Moko thinks of Mei-Li and tells himself he must go on for those he has left behind. Moko's heart lightens as he thinks that one day his travels will bring him back to those he loves.
