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 and Mei-Lei head off to the forest to pick some plants that can't be found anywhere else. Moko is following Mei-Lei's lead as she knows what to do. She picks a leaf and lets it float away, and Moko picks it up. All of a sudden, both his feet sink into the quicksand and he can't get free. Some fishermen come to his rescue and they pull him to safety. Moko and Mei-Lei head back towards the village thinking that the forest is jealous and possessive, since it clearly wanted to keep every leaf and every plant for itself.
