12 Principles of Animation: Exaggeration

Exaggeration is using unrealistic proportions and overly expressive reactions to create an animated feeling of intensity.

Though this isn't the best illustrated, I think that the camera shake, the elephant's screaming expression, and the jaws of the mouth show clear exaggeration of the given sound effect of the scream. I feel like the exaggeration of the mouse would be more noticeable if the staging of the elephant was less central, and the proportion of the mouse was not so realistic and possibly started larger. (Or the elephant started smaller).
