|Onyx Tile World|
As its name suggests, the world is mainly filled with gray tiles, having little else in terms of atmosphere.
As of 0.100c, this area is a dead end and has had all of its shortcuts removed, leaving only the maze-like structure of its floor tiles.
Interacting with the pink slime-like creature ("to the Fairy Effect area" on the old map) turns the tiles red. This will cause a second pink slime-like creature to appear, on the center of the platform Urotsuki initially landed on, that will teleport Urotsuki to Downfall Garden B.
