Hazy Maze Cave
Hazy Maze Cave is an underground cave level and course six in Super Mario 64 and Super Mario 64 DS. In both games this course is located in the basement of Princess Peach's Castle.
As its name implies, the Hazy Maze Cave is a maze which features a couple of areas that can be accessed by finding your way through alcoves and passageways inside the cave. The maze map can be found in every area of the maze. Some of the areas include a toxic maze, an elevator, an underwater lake (where Dorrie can be found) and a secret path where you have to fight against streams of water in order to gain two more Power Stars.
This is one of the few levels not accessed via a painting; instead, you must enter the door to the left of Lethal Lava Land and jump into a pool of liquid Goop inside.
