The tone is set, Grandpa Stub is well into the wind. He checks, does skateboard slides, makes his guitar and his two-wheeler roar in My special ship and obviously has more than one trick up his sleeve... He is the grandpa everyone dreams of: festive, surprising, modern, rock, tender and endearing. Wearing docks and white glasses, this unusual character proves that Ladybirds don't like hip-hop! and that glasses are really cool. He's on edge in La nuit où tu deviens grand or Les migrants. He is relevant and funny in C'est bête une mouche or Mère Téréchat. He generously invites his entire audience on a trip to Perpète-lès-Oies but nevertheless keeps both feet firmly on the ground when talking about Des poux qui rendent fou, or evoking harassment in Il faut le dire aux gens. A perennial observer of children's daily lives, he ironises on the overload of weekly activities in Moi je dis stop ! and without ever losing his characteristic humour, he invents a general day of obedience which, in order not to disappoint anyone, officially falls on Saint-Glinlin.
