Vakarma has been narrating everyone's actions for a few days, and no one has a private life anymore. It has to stop.

Sirielle, the family siren, has disappeared. It's time for MaXi's family to head to the dealership to get a new ride.

MaXi, Pierre and Olivier have been sleeping badly for several nights; nightmares disturb their sleep. MaXi therefore decide to go investigate in the world of dreams. There they will realize that Aranée, the tiny spider in their house, is perhaps no stranger to this phenomenon.

MaXi have to separate so that Xilo can take his singing lesson and Mara her Fas-Tchi lesson. However, a spontaneous winter falls on Pianoville, preventing Jack from driving off to fetch them.

Germinator members want to add a new member to their group. After many unsuccessful auditions, they realize that Molo, the plant growing in the room, is a talented multi-instrumentalist.

On their way to Xilo's MantaSkate practice, MaXi, Viola and Olivier come across coYOtes... all naked! They realize they've been robbed of their fur by a gang of fashionista poachers.

Pierre challenges his children: crossing the labyrinth of Violonville. The last to arrive at the exit will have to clean Jack's barn. As Pierre is blind, MaXi are convinced to succeed.

A new robot arrives in Pianoville, at MaXi: Bernardo, the Italian seductive robot. He seems to be under some kind of robot secret, but no one seems to be able to tell more.

On a cloudy day, Molo is out of sync with the rest of the group and thinks of being replaced since, in any case, he will never be able to accompany them during shows. The members of Germinator look for a solution, but it is Olivier who solves the problem by putting Molo in a pot.

The family receives the Cellos for supper. Petunia wants the house to be spotless. The parents therefore send MaXi to wash the tablecloth and napkins in the laundry. Once outside, surprise! The towels are already clean. MaXi then decide to use the laundry money to go to Lunatic with their friends.

The rain threatens to cancel the MantaSkate competition in which Xilo must participate. He and Mara swap bodies with their Totems in broad daylight to go meet the Celestial Manatee and beg him to stop the rain for the competition.

Pierre gave MaXi an assignment: find proof of man's impact on the environment. MaXi go to consult Plato, but he is more confused than ever. They then meet Tuba, who shows them her new invention: a time machine.

A meteor shower is announced soon in Pianoville. Pierre decides to build a cabin in Bémol so that the whole family can watch the show. However, they do not have the right tools and their attempts are unsuccessful.

Petunia presents her family with plans to expand her factory, but much to Mara's chagrin, these renovations will encroach on a wasteland. Waves are extremely rare plants with incredible properties.

Plato complains to MaXi that he doesn't have a real friend. Everyone talks to him through his regrowth and no one comes to visit him anymore. MaXi decides to introduce people to her, but no one agrees, until they think of Jack. At first reluctant, Jack ends up getting along very well with Plato; a bit too much, even.

The members of Germinator present their brand new track to Olivier. It's the first time they've played in front of an audience and they're so stressed that things don't go as planned. Mara suggests they do some meditation, to re-synchronize with Vakarma's rhythm.

MaXi need money to record a demo with Germinator, but Pierre refuses to finance them. He finds that he and Petunia already give them a sufficient allowance; if they want more, they will have to find a job. He tells them about Tuba, who just needs help getting rid of her old barn, but MaXi refuses.

It is the Day of the Totems, when we hold in Pianoville a big party dedicated to the Totems. MaXi can't go there, because they have to babysit Olivier, who has a cold. They decide to still organize Olympics at home with their Totems.

Olivier is sad because he cannot go to the dream world, and he finds his dreams extremely boring. The family mobilizes to stage a dream in their room during the night. Olivier recognizes them and does not believe them, but he enters the game all the same.

Gustave puts the Lunatic up for sale, because since the opening of a branch of the famous Café Pépo around the corner, he has hardly any customers. MaXi and the members of Germinator decide to organize a benefit show to keep customers coming back.

It's autumn, and MaXi and Olivier have to pick up the dead leaves to make compost. MaXi have no desire to do chores and invent a story to Olivier about the autumn monster, which they must go to investigate in the dream world.

It's Jack's birthday, and everyone has gathered to surprise him. Olivier made him a beautiful drawing with multicolored rocks that fell during the meteor shower. Jack is very emotional and his tears suddenly erase Olivier's drawing.

Molo wonders if the Great Trees can still hear him and if he can still impart his knowledge to them now that he is potted. MaXi decides to take her to see Plato, who may have some answers to her questions.

Petunia will receive the whole neighborhood for the lunar solstice, in two days. She wants her reception to be even more memorable than that of Blanche the year before.

Pierre reprimands MaXi for not bringing the recycling paper bin to the stationery as agreed. They left it in front of the house, and all the leaves spilled onto the street at the first gust of wind. MaXi goes out to collect everything and is helped by Gustave, who was passing by.

MaXi's parents tell them that today is a big day. When they were born, Vakarma spoke to Pierre and Petunia to tell them that MaXi were very special children to whom she had granted special powers.
