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 thinks that somewhere lies a creature that blows so hard that it makes the boughs of trees quiver and creates the desert dunes. He believes that the clouds flee before the wind comes because they are afraid of the creature. He decides to go look for it. Tired after walking beneath the hot sun, a fresh, light breeze makes his rest more pleasant. However, the creature is actually the Harmattan blowing over West Africa.
