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, the snow's thaw is drawing to a close and the mountain is shedding its white robe. Alarick and Moko are fishing in one of the mountain's springs and are catching nothing. They ask an old wise man to tell them where there might be fish. He points them towards the road to the "Ancient Mountain." They follow the road the old man told them about and reach a green luxuriant hill covered with fruit trees and streams. They think that this hill--smaller than their mountain, richer and greener--younger and simply hasn't grown up yet. Moko and Alarick explore the natural process of erosion.
