Character development sketches appear behind the initial end credits.
The very last thing seen at the end credits is a short animation of Maynott in the same prison cell as Albert and the thief from earlier, forced to listen to them singing.
Part-way through the end credits, there is a short animation of Raoul, Lucille, Francoeur, Maud, Emile, Charles, Carlotta, and Pâté flying the airship over Paris, scattering the super sunflower seeds in order to drain the flooded Seine.
