Pierre was the stage manager for the opera where Sly Cooper and Carmelita Fox met. He tried to use Sly's distraction so that he could steal Pachyderma Tuskinanny's Diva Diamond, which was hidden with all the other jewelry for the costumes. It was later stolen from him by Sly, who put it around Pierre's neck, tied him up, and dropped him onto the stage where Carmelita, Inspector Barkley and Pachyderma were.
