Oswald the Lucky Rabbit Mouse cartoon to be filmed was "Plane Crazy" in the summer of 1928, but it was produced as a silent and held back from release. The first Mickey Mouse film with a synchronized soundtrack, "Steamboat Willie", reached the screen that fall and became a major hit, eclipsing Oswald. "Plane Crazy" was later given its own synchronized soundtrack and released on March 17, 1929. Mintz, meanwhile, opened his own studio consisting primarily of former Disney employees, where he continued to produce Oswald cartoons, among them the first Oswald with sound, "Hen Fruit" (1929). While things were going in Mintz's favor, animators
Oswald the Lucky Rabbit together with other anthropomorphized toys. These included Toby Bear, Maggie Lou the wooden doll, Hi-Yah Wahoo the turtle-faced Indian, and Woody Woodpecker—depicted as a mechanical doll filled with nuts and bolts (hence his "nutty" behavior). In 1944, with the addition of writer John Stanley, the stuffed animal motif was dropped, as were Maggie Lou, Woody, and Wahoo. Oswald and Toby became flesh and blood characters living as roommates in "Lantzville". Initially drawn by Dan Gormley, the series was later drawn by the likes of Dan Noonan and Lloyd White. In 1948, Toby adopted two orphan rabbits for Oswald to raise.
