Dire, Dire Docks

Dire, Dire Docks is the ninth course in Super Mario 64 and its DS remake. The entrance to the course is through the Star Door to the left of the castle's main room of the basement. Thirty Power Stars are needed to unlock the door. The entrance to Dire, Dire Docks is a large, water-like substance and walking or jumping through it will bring the player to the course. Before collecting the course's first Power Star, Dire, Dire Dock's entrance is covering the way to Bowser in the Fire Sea, but once the Power Star is collected, the entrance to Dire, Dire Docks moves back to the end of the hall, opening Bowser in the Fire Sea. Additionally, Bowser's Sub in Dire, Dire Docks will not move until Bowser in the Fire Sea is completed.

Layout
A majority of the course is underwater. The player will immediately start falling into a body of water, and in the DS version of the game, there are some Black Bricks and Skeeters on the surface. Below the surface are Cheep Cheeps, a Manta, a cyclone that will make the player lose a life if they get trapped in it, and several treasure chests along the bottom. A large tunnel connects the two areas of the course, and there is a place to come up for air halfway through the tunnel.

The next area of the course has several Clams along the floor, a cage containing a Power Star to the left, and a grate spouting Water Rings. If Bowser in the Fire Sea has yet to be completed, there will be a large sub on the water's surface. Otherwise, the sub will be missing and a large exit into the castle's courtyard will be open to the south. Above the surface is a boardwalk with Metal and Vanish Cap Blocks, as well as a Purple Switch that creates Blocks to the platforms above when stood on. Several poles slide across the ceiling of this course, though they will not appear is Bowser's Sub is still present.
