Ruins

The level "Ruins" is a level that appears in personalized copies of Super Mario 64. This level seems to be an edited version of Whomp's Fortress, with no missions or stars present.

The only known documentation of this stage is in a YouTube video that was uploaded on January 20th, 2021. Link: https://youtu.be/9fq5ONYDDoU

Upon entering the level, a jingle plays. This jingle typically plays during normal gameplay when a puzzle is solved. After the jingle plays, the level is completely silent.

The player makes their way up to the top of the fortress, encountering a invisible Boo, and a Piranha Plant that's model is swapped with a deformed MIPS the Rabbit.

Once the player finally reaches the top of the fortress, a pink Bob-omb Buddy is faced away from the player. When talked to, the Bob-omb greets the player, and shortly explains what the area is, and what happened to the enemies. The Bob-omb then mentions that "it" will be back, and come for the player, before saying goodbye. It is currently unknown what this "it" actually is.
