Robespierre is Jaune Tom's friend. While he is sometimes inconsiderate and reckless, he does mean well, and is clever and resourceful.
Role in the film
When Mewsette leaves for Paris, he and Jaune Tom arrive in Paris, searching for Mewsette. Robespierre and Jaune Tom arrive just at that moment but are waylaid by one of Meowrice's shadowy cat henchmen and barely escape drowning in Paris's famous labyrinthine sewers. By coincidence, Jaune Tom displays his incredible mouse-hunting skills in front of Meowrice (known as "Virtue-Mousety"), who sees a money-making opportunity, gets them drunk, and sells them as mousers to a ship bound for Alaska. On the ship, Robespierre consoles a depressed Jaune Tom, telling him that any problem, regardless of size, can be broken up into manageable pieces, by remarking that even the mighty ocean is made up of little drops of water. Meanwhile, not long after they reach Alaska (a howling wilderness of snow), he and Jaune Tom strike gold. Now wealthy, the two cats hurry back to Paris. But Meowrice and his goons capture Mewsette. She is taken to the Gare du Nord railway station, en route to a boat to America, and all hope seems lost, when Jaune Tom and Robespierre arrive. They have been aided by Mme. Ruebens-Chatte, who is irritated that her own "brother" double-crossed her and tears up the worthless check. In a humorously over-the-top fight scene inside the boxcar of a moving train, the three heroes defeat Meowrice and pack him into the crate intended for Mewsette, doubtless that this will be a nasty surprise for Mr. Phtt. Afterwards, Robespierre, along with Mewsette and Jaune Tom, are enjoying the high life in Paris that Mewsette was seeking when she left home.
