Scary Sewer Maze

Scary Sewer Maze is an area in B3313.

Description
The area consists of an underwater section and a surface section. The former is practically unescapable, as it is too low to jump out of back into the surface section, and can only be traversed linearly through a few rooms. The latter, however, is mainly a maze consisting of several, almost identical rooms and hallways between them.

Origins
The area's layout appears to be an original creation. Textures are taken from beta versions of Super Mario 64.

The music is the "Cave Dungeon" theme from the same game's OST.

Plot significance
Deep within the maze, the player can find a room inhabited by a Shadowy Figure.
