Mickey Mouse universe
In "Plane Crazy" (1929), the first produced Mickey Mouse story, Mickey is seen at a farm. In all of his early films Mickey is in a rural setting, but most commonly at a farm. This setting was succinctly presented in the first sentences of one of Mickey's first storybooks:
The Karnival Kid
The Karnival Kid, also known as Carnival Days, is a 1929 American animated short film directed by Walt Disney and Ub Iwerks. It was produced in black and white by The Walt Disney Studio and released to theaters by Celebrity Productions. It is the ninth film in the "Mickey Mouse" film series, and the first in which Mickey speaks. (During his first eight appearances Mickey whistled, laughed, cried and otherwise vocally expressed himself.) Mickey's first spoken words were, "Hot dogs! Hot dogs!", the voice being provided by someone else other than Walt Disney.
