Spirits that appear occasionally in cemeteries.
The cemetery is a reward building in SimCity 4 which increases the mayor rating a small amount in the city.
It also reduces the air pollution near it, but it generates a small amount of water pollution itself.
It can be obtained some time after a House of Worship is built,or it can sometimes be rewarded from missions for Dr. Vu.
Occasionally, in the cemetery, ghosts and zombies would roam in the cemetery, and would disappear afterwards.
