The Skateboard Saga (1986)

After a boy is knocked off his orange skateboard by a car, the skateboard continues on its way, developing a mind of its own and wreaking havoc on innocent citizens until it is stopped in its tracks by a clever little old lady with a walking stick. The eight minute saga features live action, animation, claymation, pixelation, stunts, models, puppets, special effects, superheroes, kids, animals, snails, - and no actual dialogue, just music, sound effects and "wordless dialogue" which consists of mumbled sounds to convey the appropriate emotion.
