The series features Ariol, a little blue donkey: his daily life as a schoolboy, his best friend, the little pig Ramono, his loves (Pétula, a pretty little cow with freckles), his collections (like the Chevalier Cheval's album or collectible cards), his holidays with his grandparents (Papi Atole and Mami Annette) ... as well as "Le Chevalier Cheval", a comic book and cartoon character.
