Twilight House is one of the six Battle Stages in Mario Kart DS. It is in the middle of a forest, but has many areas where you can fall into a dark void (or bottomless pit). This course might possibly be based on Twilight Town from Paper Mario: The Thousand-Year Door.
This course reappears in Mario Kart Wii as a Retro Battle Stage. The course has been graphically updated with very little changes other than that.
