Le soir, Moko médite en regardant l’horizon, Meï-Li s’approche pour lui tenir compagnie. Tout d’un coup, un bruit sourd et continu derrière la plage, se fait entendre. Meï-Li a peur, mais Moko veut en savoir davantage. En s’approchant des collines, le bruit est de plus en plus fort et Meï-Li a de plus en plus peur. Moko décide donc de faire le tour de la dune seul. C’est alors que ce grondement s’atténue et se transforme en chant. Moko revient et explique à Meï-Li que c’est le sable et la terre qui chantent ensemble. Elle décide de chanter elle aussi. Moko se dit que la dune enchantée appelle au voyage et que c’est sans doute son dernier jour au village…

As the first rays of dawn appear, Moko and Mei-Li head off to the forest to pick some plants that can’t be found anywhere else. Moko is following Mei-Li’s lead as she knows what to do. She picks a leaf and lets it float away, and Moko picks it up. All of a sudden, both his feet sink into the sand and he can’t get free. He calls out for help. Some fishermen come to his rescue and one of them throws him a line and they pull him to safety. Moko and Mei-Li head back towards the village thinking that the forest is jealous and possessive, since it clearly wanted to keep every leaf and every plant for itself.

Intrigued by the name given to the mountains in the horizon, “the Hills of the round Earth”, Moko ventures off to see if the Earth is, in fact, round. An old wise man tells him that yes, if he were to walk in a straight line he could very well go all the way around the earth and come back to his starting point. Moko does as he is told and travels all the way around the Earth and returns back to his village, but since he didn’t have the feeling that he was walking around a sphere, he continues thinking that the Earth is flat.

That morning, Moko tells himself that it is time to leave Mei-Li’s land and he gets his raft ready. A man tells him that he must take the route of the great plains to continue his journey. Moko goes to the village to bid farewell to Mei-Li who has made rice cakes for him. One morning a few days after his departure he reaches the famous route where the horizon seems never-ending. As he walks a great gust of wind makes him fall and drop his precious stone. Seeing it on the ground, Moko thinks of Mei-Li and tells himself he must go on for those he has left behind. He goes on while clutching his stone in his hand. Moko’s heart lightens as he thinks that one day his travels will bring him back to those he loves.

Alarick’s country is very strange. It has been many days now that night has not falen, and no one seems to be worried. Moko decides to head towards the horizon to see what is keeping the sun from setting and Alarick goes with him. Along the way, Moko tries to lull the sun to sleep with a lullaby from his country. The sun looks like it will set, but stops short and rises again. Perhaps the ocean is frozen at the horizon and is keeping the sun from setting. He decides to ask the fishermen and one of them responds that the world is filled with such mysteries and that it is more precious for him to learn the secrets of his friend than that of the sun.

Moko se demande pourquoi les nuages viennent tous pleurer au même moment sur son village. Qu’est-ce qui les rend si tristes ? Il questionne le vieux du village qui lui propose d’attendre la fin de la saison des pluies pour comprendre. Une fois les pluies terminées, Moko retourne voir le vieux. Ce dernier lui dit que la réponse est dans les champs et les plantations. Moko découvre en effet que la pluie a permis de faire pousser tant de choses, que le village ne manque de rien. Il pense alors que les nuages ne sont pas tristes lorsqu’il pleut, mais qu’ils offrent toute leur eau pour que la terre soit fertile.

Ce soir-là, la marée est basse et le bateau est à sec. Moko et Alarick jouent des percussions et de la flûte pour passer le temps. Soudain, on dirait que leur musique est accompagnée par un étrange chant. Ils décident d’aller voir d’où vient cette musique. En avançant sur un sentier montagneux, des centaines de roches qui se ressemblent, se dressent comme des humains dans la pénombre. Un vent fort se lève et la musique étrange reprend. D’abord effrayés, Moko et Alarick se disent que les rochers font une chorale et se mettent à jouer à leur tour. À la tombée du vent, ils regagnent leur bateau, heureux d’avoir participé à la symphonie des rochers chantants… qui sans doute s’ennuyaient de ne voir personne…

Moko sees the ocean for the first time. He thinks it is a huge river or lake, but when he tastes the water, he notices that it is salty. He wonders what sorcerer would have played such a trick. Back in his village, he asks an old wise man to cast a spell on the village’s river so that the drinking water never becomes salty. The wise man reassures him that this is not necessary, the water will never be salty and Moko is grateful that someone has already thought of protecting the village’s river.
