Yakari meets his friend Great Eagle in his dreams. His wish of seeing him “for real” will come true the day that he manages to be like him. So Yakari tries to fly, but in vain. Then he saves his friend Rainbow from an attack by a mother Puma. And finally he saves the life of the mustang Little Thunder, stuck on a mountain ledge. It is with Little Thunder that Yakari discovers his formidable talent: he can talk to the animals. As a reward for his numerous exploits, Great Eagle gives Yakari his most beautiful feather. But nobody in his tribe will believe the little Indian…

Spring is a long time coming on the Great Prairie. The Sioux tribe awaits the return of the buffalo. The tribe is hungry. Yakari, who lives his dreams, goes with Little Thunder to look for the herd led by White Buffalo. The two friends cross a scorching desert before finding themselves faced with a wall of rocks. Yakari scales the wall and discovers green pastures where the much-awaited herd is lingering. The bison take refuge there when they lack food during the migrations. Yakari is the first human to walk these fertile lands that are hidden in the desert. Knowing that the Red Men need them, the buffalo obey their destiny. Yakari will keep his discovery a secret.

Yakari discovers a colony of beavers busy building their dam. There we find Thousand-mouths, the short-tempered building site boss; Wooden-Dam, the smiling old wise man; Wooden-Bed, the sleepyhead; Double-Tooth, the eternally inspired sculptor… and last but not least Little Linden Tree, a lively kid. While they are bathing, this infernal little beaver disappears. Yakari will find him exploring the underground waterways of the river. Linden Tree will, of course, receive his first smacking (Rough-Bark, his father, is so worried!) and Double-Tooth will finally be able to present his masterpiece to the amazed colony.

Something very serious is happening in the High Hills. Several animals have disappeared. A terrible grizzly has captured them and treats them as slaves, forcing them to find food for him. Arming himself with courage, Yakari bravely decides to face the vile tyrant. But how can a child stand before the wild animal? Great Eagle advises Yakari to wait for winter, when the bear, satiated, will sleep...

There’s panic among the beavers. A pelican, fiendishly sick with a cold, makes an emergency landing among them. Not only does this undesirable guest keep all the neighbourhood awake with his monstrous sneezes, but he’s dying of hunger. Yakari and Little Thunder bring him to the otters, who cram him with fish. The pelican puts on weight again quickly, but his thundering cold persists!

Tormented Wolf, a warrior from Yakari’s tribe, has an obsession: to take his revenge on the wolf who attacked and injured him three winters before. This wolf limps... Yakari has crossed the path of Three Legs. He is afraid, but a dream and the intervention of Great Eagle, his totem, encourage him to join the wolves. He will earn the trust of the pack’s leader...

When a storm takes them by surprise, Yakari, his best friend Rainbow and his pony Little Thunder take cover in a cave. They discover when they come out of their refuge that the hill they are on is surrounded by rising water. On this new “island,” they befriend a wounded moose threatened by a merciless predator...

A strange eagle has wounded a brave from Yakari’s tribe and stolen his talisman. To recover it and allow the man to wake from his unnatural slumber, young Yakari will have to climb a mountain to find the eagle’s nest. Forced to go alone when Little Thunder can’t follow anymore, he will have to make new friends–with sure feet and warm coats–and brave the majestic bird’s proud anger.

When the beavers bring Yakari a battered old canoe, the young Sioux and his friends repair it and go for a little trip—and find more adventure than they bargained for, in the person of a father coyote. Fortunately, their new friend is up to his reputation for cunning: When Buffalo Seed is cornered by an angry puma, it will take all of the coyote’s tricks, combined with Yakari’s bravery, to get the young hunter out of his predicament.

While trying to save a bear cub from drowning, Yakari falls into the river and hits his head on a rock. By the time he washes ashore and is found by a distraught bear mother, he has forgotten who he is. The she-bear is convinced that he is her son, turned into a human by the Bear Spirit, and begins to train him for his new life. Can Yakari’s friends find him before he disappears into his new world for good?

Nanabozo, the Great Rabbit, is... well, a giant rabbit. He’s also a powerful sorcerer, and Rainbow’s spirit guide, as Great Eagle is for Yakari. When he appears to the young Sioux to tell him his charge has disappeared, little Yakari is swept up in a quest that will make him turn into a giant, run on smoke, fly, and travel to the ice banks where the polar bears play.

Little Thunder is quite an astounding pony, and he and Yakari truly are the best of friends. So when upon waking up one morning, he discovers that his mount has left the village, the young Sioux boy is devastated. He tries to find his friend, but is forced to give up as the trail grows cold: whatever it is that drives Little Thunder, he’s heading due south as fast as he can. What is it that calls out to him?

Yakari wakes up one morning to find a series of arrows forming a trail. Following it, he soon finds himself the exasperated victim of pranks, mockeries and other vexing tomfoolery by an unknown bear cub. The young joker’s hideout is a massive burrow, with multiple galleries and entrances. It’s all very innocent and tame, but even the most harmless of pranks can turn dangerous when bad luck strikes...

Yakari gets to know the ways of the lord of the plains: the buffalo. After a hunt that brought the tribe much needed supplies, Yakari is visited in his dreams by the buffalo, killed the day of his birth, whose pelt still serves as his blanket. Intrigued, the young Sioux and Little Thunder go see the great herd. From encounter to encounter, and by helping a young mother and her newborn calf against a particularly nasty wolf, Yakari learns to know those majestic animals so important to his own people’s survival...

Yakari learns from the tribe’s elder that the Sioux haven’t always been the magnificent riders they are now – indeed, that there was a time they didn’t even know what a horse was. Shaken, he speaks a little too demandingly to Little Thunder, wounding his four-legged friend who immediately runs away. Devastated, the young boy will have to track down his companion and find a way to earn his forgiveness if he ever wants to share a gallop with him again...

The Beavers are very worried: Linden Tree, Yakari’s yound and mischievous friend, has lost his appetite for … well, everything. And his people have no time to devote to him, as they must repair their precious dam, damaged by heavy rains. While the young Sioux attempts to dispel his friend’s melancholy, Thousand-mouths suddenly realises he is several labourers short of a full work gang. Is something in the lake going after the hard-working beavers?

One day when heavy rains force them to play inside, Yakari and Rainbow are startled by a strange sound. To their amazement, it’s followed by their whole tipi suddenly taking off and flying straight north, with them inside! After several hours of a not entirely pleasant journey, they’re greeted on landing by Rainbow’s spirit guide Nanabozho, the Great Rabbit, who wants them to meet the inhabitants of the great north. Among those is a mysterious white bird …

In the middle of the night, a daring thief from another tribe makes off with the horses of Yakari’s people. Only Little Thunder managed to escape him by fleeing into the forest. While the warriors hurry after their precious mounts, Yakari goes in search of his friend … who is himself trailing the thief! Once the two groups converge near a huge camp, Yakari will have to display extraordinary cleverness to help his folk…

In the middle of winter, while Yakari and his friends play in the snow, the tribe’s hunters kill a terrified wapiti. A welcome catch, for the stocks of food are running low. But the next day, all the meat that had been left to dry has disappeared! The hunters set out after the thief, and soon begin to suspect a bear. Yakari then decides to visit his furry friends to identify the culprit …

After a long rainy spell, large stretches of the prairie are flooded, much to the displeasure of most of its inhabitants. Yakari visits his friends to make sure everyone is all right, then falls asleep that night and dreams of clouds mysteriously coming out of the water. The young Sioux’s dreams are not always completely random, though, and the next day he rides out in search of signs. What he will find will soon unite all his friends in a desperate rescue mission …
