Ep 21. Season I - Episode 21 - The Oxygen Plants

Passing through an Oxygen Forest, the Doodjies come upon the hostile Chwan who hunt and hoard more Ozums (little animals that help to keep nature in balance) than they can eat. Enyo learns from the spirit that it's the Ozums who release the oxygen from the plants and without their help, the air goes bad. Enyo needs to free the animals to save the forest and his tribe.
