 In keeping with the show's animation style, Cartman is composed of simple geometrical shapes and primary colors.He is not offered the same free range of motion associated with hand-drawn characters; his character is mostly shown from one direction, and his movements intentionally jerky.Ever since the show's second episode, "Weight Gain 4000" (season one, 1997), Cartman, like all other characters on the show, has been animated with computer software, though he is portrayed to give the impression that the show still utilizes its original technique.
