Hotel Floor

The Hotel Floor is an anomalous area found in 1 copy of Super Mario 64. It is a grey, dungeon-like area with only one Boss Fight, no courses, and only 2 available Stars.

Accessing the Hotel Floor
The Hotel Floor is accessed by defeating Bowser in the Sky in copies that include the Hotel Floor. Instead of Mario returning to Peach's Castle, he will be sent to the Hotel Floor, before the screen turns black with text appearing;

"The Unreleting WeeGee is preparing for your arrival. Good Luck!"

The Boss Fight
The Boss in this stage is Luigi, albeit upscaled massively to approximately size of the large snowman in Snowman's Land.

He attacks the player by firing lasers at certain portions of the arena, telegraphed by a color change in his eyes. He may also fire lasers directly at the player in certain sections. Luigi can be damaged by waiting for him to begin Laughing, and then diving towards his head, damaging him.

To date, the round has never been beaten, as on the only recorded copy that included the boss, the player died when attempting to hit the boss a second time. The player then recieved a Game Over, and the Hotel Floor dissapeared.
