A South Parker is a species of human-like living paper doll with no known ancestors. South Parkers remain in height of an average 4th grader throughout South Park. Also, they no longer use bad words as the ones that use them are not tolerated by any sapient species/being, plus they don't need mature stuff to do so.
They are extremely peaceful and gentle towards all sapient species and sapient beings, except vampires due to bloody conflicts with them. They are omnivores that feed on the same kind of food as many other sapient species and sapient beings.
