One skull is from the Chief of a tribe that lived on modern-day Spooner Street. Peter Griffin finds it when building a movie theater in the Griffin backyard in "Petergeist" and names it Chief Diamond Phillips. Peter used the skull for many purposes and activities. The excavation led to anger in the spirit world, leading to the abduction of Stewie Griffin and the disappearance of the house. The skull ends up in Carrot Top's care, the Griffin Family retrieves it, buries it, and everything is returned to normal.
