Mickey's Fire Brigade (1935)

Continuity mistake: When Donald Duck is holding on to Mickey Mouse when Goofy is dangling on the ladder, you can see there is a window underneath Donald, but when he has his feathers burned in the next shot, the window has disappeared.

Trivia: When the fire creatures dance on the piano keys, the tune they play is "Who's Afraid of the Big Bad Wolf?", which was featured in the 1933 Walt Disney cartoon "Three Little Pigs."
