With "Les croquillards" (1957), Macherot placed his characters to the island of Croquefredouille, a fictitious country populated entirely with "civilized" animals, complete with technology, police, government, and so on. The action surrounds the introduction (by Anthracite, of course) of carnivorous animals to the island (the 'croquillards' of the title). The story is darkly comic, with many characters ending up as gourmet meals for the predators. Strangely, Macherot's publisher, Le Lombard, refused to release the "Croquefredouille" stories in book form until 1980.
