Rigodon

Prior to working for Willy Fog, multi-talented French feline Rigodon (occupying the role of Passepartout from the original novel; however, Brazilian, Finnish, French, Greek, Hebrew and Slovak dubbing named him Passepartout) was a circus performer, but wanting to escape the travelling life of the circus, Rigodon sought out employment as a manservant. His first attempt was a failure, as he worked for a gentleman who constantly travelled, and so he sought out employment with Willy Fog, knowing that Fog's strict routine meant he never travelled far. Rigodon's hopes of a quiet lifestyle, however, were quickly dashed when Fog accepted the wager to travel around the world in eighty days.

Nevertheless, Rigodon dutifully accompanies his master on his trip, his circus-born agility and daring coming in handy on more than one occasion.
