The 0 Life Area is an area in Super Mario Star Road, only accessed when a player runs out of lives. The area is entirely grayscale, and has a path leading to a large hole. There are also a few Boos along the path. In order to exit this area, the player will need to go to the end of the path and jump into the large hole, which returns the player to the start screen. Getting killed has the same effect.
- There was apparently an image of this area in color. However, in the game proper, the entire area is in grayscale, except for objects such as Mario, coins, and Boos.
- While in this area, the HUD shows that the player has 3 lives and 0 stars, regardless of how many stars had been collected before.
