Rigodon

Rigodon is a multitalented French feline who worked as a circus performer before seeking a quieter life as a manservant. He chooses employment with Willy Fog because Fog's strict routine seems unlikely to involve much travel, only for that hope to collapse when Fog accepts a wager to circle the world in eighty days.

Rigodon nevertheless accompanies him faithfully, and his circus-trained agility and daring repeatedly prove useful on the journey.
