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 rain has just fallen and the sun is returning. A beautiful rainbow fills the horizon. Moko would like to take a few colors and bring them back to his village to offer them to a friend. He walks toward the rainbow, but the closer he gets, the more the colors disappear. Disappointed, he heads back home... and the rainbow reappears in the distance. He asks the village wise man how he could take a few colors from the rainbow and make a gift of them to a friend. The wise man tells him it would be better to ask his friend to come look at the beauty of the colors with him. After all, Moko tells himself, the rainbow is too big and doesn't want us to take its colors away. It comes to make the sky more beautiful. It just wants to be admired.
