Animated from the point of view of a small child. The viewer is jumping down a suburban street, and progressive jumps are higher and higher. The viewer/child lands in various city settings, a jungle, a battle field, the depths of Hell, and finally back to the street where the adventure began. The film is notable for the use of perspective in pre-CGI animation. [source]
