Tubbytronic Superdome is the name of the Teletubby House, and a location in the Main Land.
The House is usually the starting location of Tinky Winky.
The area of the beds is on fire, and the central machine seems to malfunction. It is possible to go inside from the roof and the windows.
In Slendytubbies II, the house is flooded, and everything is off.
