Even the slightest movement will keep your character alive. Sometimes an action that feels believable in traditional animation, looks too cartoony in computer animation. Because of the realistic look of computer animation, an animator need to be aware of how far to push the motion. The motion should match the design of the character and the world. Animating very cartoony motion with lots of squash and stretch on a realistic looking object may not look believable, as would realistic motion on a caricatured object.
