The Seven Dwarfs (Snow White).

The Seven adorable dwarfs of Snow White and the Seven Dwarfs are able to control emotional aspects of the movie just by speaking. Dopey, Sleepy, Happy, Grumpy, Sneezy, Bashful, and Doc can convey the emotions that their characters represent. For instance, when Sleepy talks, it is possible to become overwhelmed with fatigue. Hearing Grumpy talk, you begin to feel agitated, and when Happy talks, you will often find yourself smiling. The Seven Dwarfs, although not entirely needed in order for the story to have a strong plot, have the ability to control a viewers emotion at any given point during the movie. These characters, who each look and speak in a manner that is very fitting to their names, all have the aspects needed (such as the facial expression and tone of voice) to force certain emotions out of an audience. Essentially, these characters are used to control the emotions of the audience during times of the movie when the plot alone may not be able to do so.
