The scene in the cafeteria, in which the four boys are annoyed by Pip, is a cut scene from the original version of the "South Park" pilot, "Cartman Gets an Anal Probe"; as such, the animation in that individual scene is actually traditional paper cutout stop motion, while the animation throughout the rest of the episode is done with computers. In order to illustrate the aftermath after the destruction scenes, Parker and Stone smudged the paper sets with their fingerprints and stains to make them look like scorch burns.
