Johnny lives in a decrepit, single-story house with the street address 777. The house has an extensive labyrinth of tunnels underneath. Johnny uses the subterranean rooms as dungeons and torture chambers, as well as a storage place for corpses, though he also buries the remains of his victims. The tunnels also provide him with a network to various locations, such as his neighbor Squee's residence. Johnny perceives the layout of the house as constantly changing, though he does not state if this shifting is the result of the supernatural forces at work within the house or his own psychosis. Johnny states that he found the house and moved in some time ago. He also constructed an unidentified flying object landing pad on the roof. Throughout the series, there is no case where the authorities or the police are looking for Johnny, and they seem unaware of his existence.
