During a walk, the Barbapapa family discovers a megalith. Each of the barbababies puts forward their own hypothesis about the presence of this imposing monument, how it was erected and transported here in ancient times. Barbamama then decides to pass on to the whole family the techniques that were used at that time.
Barbabright is tired of constantly searching for the same objects and has a stroke of genius: the invention of the "BAM". It is a ribbon that he wears on his head and that allows him to easily store everything. However, Barbalib quickly realizes the commercial potential of this invention and takes matters into her own hands, to the detriment of Barbabright and the environment.
Barbabelle proudly announces to her family that she wants to become a princess. Despite the warnings from Barbalib who explains to her that it is not an easy task. The whole family then decides to support her and train her in her new royal duties.
Barbabravo is moping with boredom, his brothers and sisters are all busy and no one wants to play with him. He decides to go for a walk alone. Upon his return, Barbamama asks him to tell about his day. Barbabravo then launches into an epic story, recounting how after surviving a shipwreck, he was saved by a goddess. Stranded on a distant island, he had to participate in the Olympics and face a giant.
While everyone sleeps peacefully, one may wonder what Barbabravo, Barbalala, and Barbalib could be dreaming about. After all, dreams are opportunities to learn, grow, and explore our imagination. And what about Lolita?
Barbabeau, Barbabelle, and Barbabright have built a treehouse. The other Barbabébé are curious and would like to discover this incredible place, but it is a private club whose access is reserved for members who have passed certain tests. Is it really worth it? Is the place as extraordinary as it seems? Is it worth causing discord among the Barbabébé?
Barbapapa and Barbamama have announced to their dear barbababies that they are going on a trip to Easter Island. Meanwhile, the Barbababies will go to summer camp with Mr. Strict and his twins to go camping by a lake. Excited about this idea, the barbababies will quickly realize that setting up a camping camp is not easy... But who knows, maybe it could still be fun?
Camping near a lake, the Barbababies, the twins, and Mr. Strict set sail on "Thésée", a magnificent sailboat. Everything is calm, but sailing on a lake is sometimes not so easy, especially when the wind picks up like a tornado. It will take all the courage of the Barbababies to avoid shipwreck and return safely to their parents.
