Hazy Maze Cave

Hazy Maze Cave is an underground cave level and the sixth course in Super Mario 64 and Super Mario 64 DS. In both games, the entrance to the course is located in the basement of Princess Peach's Castle behind the unmarked star door. The course has many paths and bottomless pits, as well as a large cavern that is home to a giant sea creature named Dorrie. Several maps are also placed on the walls to help the player figure out where they are and where to go.

Layout
The area the player starts off in contains a Metal Box and two paths. The one to the right is a hall with several fire geysers that leads to the Hazy Maze and Red Coin area, with the left path having a hall with a large gap the player must Long Jump across that leads to the area with the Boulders and the underground cavern.

Through the door at the end of the left path is a large pit that boulders will continuously fall into, as well as a Spinning Heart on the left side of it and a hall to the other end of the course on the right side. This area also contains a Scuttlebug and a Swooper. Up the ramp the boulders are rolling down is a ledge that holds a Power Star in the N64 version, or a 1-Up Mushroom in the DS version, as well as a door that leads to an elevator room. In the elevator room is a ring of Coins under a ! Block that holds a 1-Up Mushroom, as well as a Power Star behind a chain fence that can only be accessed through the Hazy Maze. Down the elevator is a large, circular cavern with Dorrie swimming in the water. There are two doors in this area, with the fenced-off one leading to a Power Star and the door on the ledge that the player has to use Dorrie to reach leading to the Cavern of the Metal Cap (N64) / Behind the Waterfall (DS).

The door at the end of the right path from the start of the level leads to an open area containing the level's Red Coins and the lifts needed to reach them, as well as several Scuttlebugs and Mr. Is. To the right of the room are an elevator that takes the player to the end of the course and a door that leads to the Hazy Maze. The Hazy Maze is a large maze covered in a Toxic Cloud that will damage the player if they stand in it for too long. The maze can lead to two different Power Star or back into the other room.

Trivia

 * The level Wet-Dry World uses the same music as this level and the layer of chant is heard in the downtown area.
 * With a properly timed dive, the player can actually dive forever on the left side of the gate underground once they have opened it.
 * The minigame Dorrie Dip from Mario Party 3 takes place in this course. Dorrie also makes an appearance in this minigame.
 * This is the only course in the Nintendo 64 version to have a secret level inside it.
