The Hamburger HillsCemetery is the main setting of the episode "Ghost Princess." It appears to have been established long before the Mushroom War since it has ruined buildings and other modern-day objects in it, including stairs and mausoleums. Its original name was "Hamburger Hills Cemetery," but it is unlikely that the residents still call it that. It is inhabited by many Ghosts and seemingly no other undead creatures. All the gravestones are clear enough to see through them, and have unusual colors, like orange and red.
