Aquatic Tunnel

Aquatic Tunnel is an area in B3313.

Description
As the name suggests, the area is a series of rooms, submerged in water. There are also Crystal Taps laying around, as it would be hard for the player to survive throughout the tunnel without being able to breathe occasionally. Though, there are some Spinning Hearts towards the end.

Origins
The area seems to be an original creation, excluding the spawn area, which is likely inspired from the Secret Aquarium of SM64. The wall textures are both recolored textures from the vanilla Super Mario 64, or taken from the beta version.

The music is a variation of the "Dire, Dire Docks" theme from the same game, using the music box instrument from the Piranha Plant's lullaby track.

Stars
This area has 2 stars to collect:


 * Collecting all the 8 red coins scattered throughout the stage rewards the player with a star.
 * There's an item box at the end of the tunnel with a star in it.

Leading here

 * Crimson Hallway: In the main room, go through the hole at the end of the hallway.
 * Vanilla Basement: Jump into the hole in front of the Dire, Dire Docks painting. (You need the first star from Course 9 from this, which can be found in a Checkerboard.)

Trivia

 * As the course is located in Bowser 2, getting the red coin star lets the player stay in the area, and collect the item box's star as well. However, if the player collects the red coin star in the water, and then breaks the item box with the other star in it, the game softlocks.
