Walter Elias "Walt" Disney (December 5, 1901 – December 15, 1966), was an American film producer, director, screenwriter, voice actor, and animator. One of the most well-known motion picture producers in the world, Disney was also the creator of an American theme park called Disneyland, and is the co-founder with his brother Roy O. Disney of Walt Disney Productions, the profitable corporation now known as The Walt Disney Company. Prior to this, he created the character of Oswald for Universal Pictures, who retained the rights to Oswald until 2006 when the Walt Disney Company regained them.
While he's never referenced by name in-game, he's often talked about. Mickey Mouse is surprised to find a statue of him on Mean Street that is the same as the one from Disneyland, except with Oswald the Lucky Rabbit in Mickey's place.
