Cleo Broflovski

Cleo Broflovski is the deceased mother of Sheila Broflovski, but unusually she shares her daughter's married name.

Cleo is buried in the South Park Cemetery and her grave states she died in 1999, the year the episode was set in. However, Sheila states in the Wacky Molestation Adventure episode that she has been dead for three years, so she may have died in either 1995 or 1996.

So far she has only appeared as a corpse in the third season Halloween special "Korn's Groovy Pirate Ghost Mystery" when the boys dug her up in order to frighten the 5th Graders (who are now the 6th Graders). During the course of the episode a dog ate the corpse, but later regurgitated it to the disgust of everyone at the Halloween festival. Later, the boys managed to frighten the 5th Graders with her.

In the sixth season episode "The Biggest Douche in the Universe" the psychic John Edward "receives a message" from Cleo for Kyle Broflovski stating that he is to look out for four white doves, which he sees at the New York Airport (having travelled there to feature on the show). Kyle sees the four white doves on an advert for a Jewish school named Jewleeard which he joins. After some convincing from Stan Marsh he finally realises the physic was just cold reading and returns to town stating that Cleo is "dead and gone forever".
