Carlos contre les allergènes

Véronique is so busy organizing the gourmet fall party that she forgot the food. Her only hope is a farm that may be haunted. Boo!

Mademoiselle Bille-en-Tête and the class scour the internet to find a digital Arnaud before Jyoti's grandmother accidentally deletes it.

Children learn to see the world through the eyes of different animals when Arnaud, reckless, loses Carlos's spleen, then makes it invisible!

As they build (and rebuild) an astromobile to explore a distant planet, Jyoti and the class learn that the failure is not so serious.

A race between the competitive brothers Carlos and Mikey takes the group to the top of a mountain of pasta, where they learn how simple machines work.

The children go in search of rain to test Jyoti's latest invention, the self-umbrella, but they end up with their heads in the clouds.

Mathematics help Raphaël make calculations in mid-flight when his cousins recruit him for their dizzying circus number.

Thomas says that trees can speak and Raphael refuses to believe it. Mademoiselle Bille-en-Tête takes them into a much noisier forest than it seems.

Everyone has to poop. But the class is not convinced that this 'brown gold' has as much value as claimed by Anne-Sophie's uncle inventor.

The bus transports Mademoiselle Bille-en-Tête and classifies her inside Janet, Arnaud's cousin, to understand why genes determine who we are.

A study trip to the center of the sun makes a dangerous detour when Mr. Réglo, the school principal obsessed with safety, decides to accompany the class.
