"Lizzy", as she is referred to in the official script, is another female 4th grade student. She debuted in "Hooked on Monkey Phonics" and had a major role in the episode "Cartman's Silly Hate Crime 2000". She and the other girls were competing against the boys in a sledding race. She taunted the boys and called them very sexist terms, such as "Butt Pirates", or "Rump Rangers".
She appeared to die at the end of the episode, when the girls sled went off a cliff and she got dragged off by a bear, though she has been seen in numerous cameos since then: As part of Cartman's congregation in "Do The Handicapped Go To Hell?"/"Probably", on a roller coaster and standing in the back of the crowd watching Cartman begging for his money back in "Cartmanland", in the crowd at the end of "Proper Condom Use", in a crowd of schoolchildren in "Fat Butt and Pancake Head" and sitting behind Kenny McCormick on the roller coaster in "Best Friends Forever", and on the swings in several playground shots.
- Lizzy wears a parka and has a sexually advanced vocabulary, making her similar to Kenny. It is unknown if the studio did this on purpose.
- Despite the fact she was carried offscreen by a bear at the end of "Cartman's Silly Hate Crime 2000", she has been shown in later episodes. It is possible that the bear did not kill her, much like the bear in "Jewbilee".
