Un grand jour de rien (Albin Michel Jeunesse)

Esteban is very disappointed because he had a little sister instead of a brother. On top of that, he thinks that she looks like a potato. To comfort him, Lisette reads him a story about a little rabbit who was shaped like a potato.

Lila wants to play with Esteban and Antoine but they prefer to play a chess game. She is sad because she thinks that the older kids never listen to her and wants to do something fun. Antoine suggests reading to her a funny book.

Lilas explains to her friends that a superhero doesn't necessarily have powers. She makes them discover the true story of Polaman, a hero like no other.

Yaël dances with Oscar and doesn't think he is very skilled because he cannot follow her choreography. Later, Esteban arrives and she makes fun of his clothes. Oscar decides to read the story of 5 friends to show that perfection is not always important in life.

Esteban is bored and his friends try to find something to do. He is not interested in their suggestions because he feels he has done everything. They suggest that he read a book, but he is convinced that he has read all the books in the treehouse.

Antoine is cooking and asks Oscar to bring ingredients to finish his dish. Oscar is a bit forgetful and forgets or loses some items. He even brings blue spaghetti.

The friends decorate the tree house because it is Lisette's birthday. Lilas makes a poster but she commits a mistake in her drawing. They comfort her by reading one of the books that will be offered to Lisette.
