Sigma's Sheer Shaft

Sigma's Sheer Shaft.
Sigma's Sheer Shaft or, as it will be referred to for the rest of this entry, SSS is an anomalous level, only found in incredibly rare levels of personalisation and it has steps to unlock. To unlock it, you must have experienced the White Eyed Chomp anomaly, you must die to it 69 times in a row. It does not matter if you reset the game. Once you've done this a massive cock, see the image on the right, will appear instead of the star in the courtyard. By doing 69,420 loops around the cock statue, a painting will unlock, replacing the doors out of the courtyard.

The Level.
The level is a maze, with the skybox and walls being pictures of SSS, or Sigma's Sheer Shaft. Once you escape the maze, the AI takes the form of SSS, or Sigma's Sheer Shaft and will eat you.

In VERY RARE cases, it is possible to ground pound the chicken, however you can only do this if you kill the 69 chicken guards wandering the maze.

If you do kill SSS or Sigma's Sheer Shaft, then you can escape through the bumhole in the floor.
