Puppetoon animation is a type of replacement animation, which is itself a type of stop-motion animation. In traditional stop-motion, the puppets are made with movable parts which are repositioned between frames to create the illusion of motion when the frames are played in rapid sequence. In puppetoon animation the puppets are rigid and static pieces; each is typically used in a single frame and then switched with a separate, near-duplicate puppet for the next frame. Thus puppetoon animation requires many separate figures. It is thus more analogous in a certain sense to cel animation than is traditional stop-motion: the characters are created from scratch for each frame.
