the sound is used to emphasize the action because the animation goes along with it, for example, the boat has steam coming out of it so the sound was almost like a train when Micky was turning the wheel of the ship it was making a cranking sound to emphasize the turning. The sound gives the film life. the uses of sound reveal something about each of the characters for example the guy that caught Micky was making angry sounds but not talking kind of showing you he is grumpy or upset about something.
