Endless stairs

"To open the door that leads to the "endless" stairs, you need 70 Stars. Bwa ha ha!"

- Bowser

The endless stairs (also stylized as "endless" stairs) are an obstacle within the Mushroom Castle in Super Mario 64 and Super Mario 64 DS. They are behind the final Big Star Door, which leads to Bowser in the Sky, the final level of the game. If the player has fewer than 70 Power Stars in Super Mario 64 or fewer than 80 Power Stars and/or is not playing as Mario in Super Mario 64 DS, they can still enter the Big Star Door, but they will endlessly climb this flight of stairs, seemingly gaining no ground, though they can easily exit through the entrance. Once the player manages to collect 70 Power Stars (80 and Mario in the Nintendo DS remake), the endless stairs finally end, and Mario will be able to access Bowser in the Sky when he reaches the top.

The "endless" stairs illusion is created by warping Mario back once he reaches a certain point. This can be easily seen in the DS remake via the minimap, as well as the fact that the ceiling at the top of the stairs is actually slightly visible in this version due to lighting changes. In either version, it can be easily seen if the player manages to get the camera in front of the character.

Trivia

 * However, a different glitch can be used to access this in the DS remake.
 * The endless stairs are similar to the, which are also endless stairs, except the latter are formed in a loop to produce the endless illusion, while the former follow the more traditional fashion of stairs by going up.
