It's the first swimming lesson for Miss Susie's Year 2 class. Alix and Paulin are very excited: no surprise there, as they are already very good swimmers. For Nino, it's a different story. He is terrified of the water but, afraid of being teased, has signed up for the dolphin group... But Nino will soon realise that he's not the only one with hang-ups: Dorian thinks he's too fat in his swimming trunks, Violette is ashamed of her warts and Hassan has a third nipple. Will Nino manage to admit his fear of water to the class?
