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, having spent the night up in the giant tree, Moko is woken up by the sound of an arrow piercing through an enormous fruit. Afraid that a giant must be coming, he climbs down the tree and tries to flee, but gets lost in the Amazon Forest. This is when he meets Totemie, a young Amazonian girl who knows the forest better than anyone. She invites Moko to her village and they walk through an incredible maze of plants, roots and trees of all kinds. Without Totemie, Moko would be completely lost. He believes the forest introduced his new friend so that he could learn a few of its secrets.
