Mickey's Fire Brigade is a Mickey Mouse short released 3 August 1935.
Mickey Mouse, Donald Duck, and Goofy are firefighters. Mickey drives a hook-and-ladder truck to a hotel fire. Donald is standing on the ladders shouting "Fire! Fire! Fire!" while Goofy is steering the rear of the truck. They arrive at the hotel and go to work.
Mickey realizes that there is a woman upstairs who needs saving. They find Clarabelle Cow locked in the bathroom taking a bath and singing to herself, unaware that the hotel is on fire. After Goofy unsuccessfully tries to warn her through the transom, Mickey and Donald break down the door using Goofy as a battering ram. Clarabelle is alarmed and thinks that Mickey, Donald, and Goofy are kidnappers. As she screams for the police, hitting them with her scrub brush, the three firefighters lift the bathtub, with Clarabelle still in it, and shove it out the window.
Clarabelle sails through the air in her tub, and slides down a ladder to the ground. The three firefighters then land in the bathtub, and Clarabelle continues hitting them with her brush.
