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.

Continuity mistake: When Mickey Mouse's fire engine arrives at the scene of the fire, you can see there is nothing attached on the bell on the engine, but when we see the bell in the next shot, it has now has a small pulley on it.

Continuity mistake: When the dressing table crashes through the roof of the house, there are various items attached to it that fall off when the ladder rises into the sky, but when we see the dressing table in the next shot, the items are nowhere to be seen.

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."
