puppet

(n.) an inanimate object that is, usually for entertainment purposes, given voice and animation by a person. this person is usually called a puppeteer or a lobbyist

puppets come in many forms, from the humble googly-eyed sock worn over one's hand, whereafter the fingers can be moved to make its "mouth" flop around like that of a fish corpse; to the marionette, controlled by long strings affixed to its joints and artfully tugged by the fingers of a mustachioed italian man. these are just examples. could also be something much better.
