Moko se demande pourquoi la lune change si souvent de forme. Voyant parfois qu’elle se lève au loin comme le soleil, il se dit qu’en avançant vers l’horizon, il pourrait s’en rapprocher et en savoir davantage. Le mieux serait même de lui poser la question. Durant sa longue marche vers un horizon qu’il n’arrive pas à atteindre, Moko voit la lune changer de forme sans cesse. Tantôt en forme de croissant comme un sourire, tantôt disque de lumière, tantôt blanche, tantôt jaune, la lune se déplace dans le ciel sans même qu’on puisse la voir bouger. Une nuit, Moko décide de regarder le ballet merveilleux de la lune au milieu des étoiles. Il se dit qu’il n’atteindrait pas l’horizon et qu’après tout, la lune aimait tout simplement se donner en spectacle pour qu’on la regarde plus souvent…

It is night time and Moko can’t sleep. Looking out to the horizon, he notices a shot of colour at the water’s surface. He wakes Mei-Li to ask her what he is seeing. Together they take a barge and set off. Under them, a rainbow of colours is dancing in the waves. Moko and Mei-Li think that the fish must be organizing a party and decide to dive in. Bit by bit the sun is rising and day is breaking. The two friends return to the village, overjoyed at the wonders of the ocean.

Moko is woken by the sound of singing coming from the other end of the beach. It is Mei-Li, who wears a hat the shape of a sand dune and whose eyes are the shape of a moon crescent. As they are walking towards Mei-Li’s village, they feel a terrible rumble and see black smoke coming from the mountain. Moko thinks this is his fault, that he has trespassed in the forbidden forest, and wants to apologize. They arrive at the edge of an enormous chasm, a veritable fire pit. To calm the mountain, Moko offers it a beautiful seashell, as Mei-Li’s ancestors did. The mountain’s rumbling stops and Moko is proud to have learned it’s language.

Day after day, Moko has been going to the shore and contemplating the rising sun. On one particular morning, he is accompanied by his friend, the village’s “wise man”. He asks his friend what he might find at the end of the world, he would very much like to go there. The old man tells him that he must leave everything behind and find out; he doesn’t know what lies at the end of the world but that he would very much like to. Moko promises to return and share his discoveries and takes off on a raft. Suddenly he is caught up in a terrible storm and he pleads with the Sea Beast to let him through. The tornado swirls around his raft and lifts him high in the sky then drops him back atop the waves, safe and sound. As the storm fades into the distance, Moko thanks the Sea Beast for keeping him safe and is now convinced that he will finally know what lies on the other side of the ocean.

Ce jour-là, le soleil est si fort que les gens ne quittent pas leur maison. Moko et Meï-Li se reposent à l’ombre d’un grand arbre. Meï-Li se demande si Moko va repartir, elle pleure et s’en va. Moko tente de la retrouver dans la forêt. Des gouttes d’eau ruissèlent des arbres comme des perles de pluie. La nuit tombe et Moko ne voit plus rien, il s’arrête pour attendre que le jour se lève. Au matin, Meï-Li est là, elle a dans ses mains une pierre transparente. Elle sourit car elle se dit que Moko tient à elle puisqu’il a fait tout ce chemin pour la retrouver. Elle lui offre la pierre pour qu’il ne l’oublie jamais. Moko s’aperçoit que la pluie des grands arbres s’est arrêtée. Il pense alors que la forêt a arrêté de pleurer car Meï-Li est consolée. Ils rentrent au village et se promettent que tout ce qu’ils découvriront dans ce monde, ils reviendront se le dire un jour.

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.

On this night, Moko is meditating, contemplating the horizon. Mei-Li comes to keep him company. All of a sudden, they hear a hollow and continuous sound coming from beyond the beach. Mei-Li is frightened but Moko is curious and wants to know what is making this sound. As they approach the hills, the sound gets louder and louder and Mei-Li is more and more frightened, so Moko decides to go around the dune on his own. As he does so, the sound changes and becomes more of a song. Moko returns and tells Mei-Li that it is the sand and the ground singing together. She decides to sing as well. Moko thinks to himself that the magical dune is urging him to go on with his travels and he knows that this is likely his last day in the village. With a heavy heart, Moko decides that at dawn he will need to pack his bags.
