Plexal Lobby

Plexal Lobby is an area in B3313.

Description
The main room of the area bears a resemblance in structure to the Vanilla Lobby, with many doors leading to different areas. A key door at the back leads to a junction room, containing several brick blocks with flames on top of them, while a key door at the front, with Peach's painting above it leads to another, which in turn leads to the central hallway room, with a series of doors as well, along with a side room.

Origins
The area's layout appears to be an modified version of 1st floor of Castle Plexus that was found on XDelta and Gronoti's old work. Most of the textures originate from the Shoshinkai beta version of Super Mario 64.

The music is a variation of the "Inside Castle" theme from the same game's OST, now in a minor scale. This variation was made by NicoSwitch and used previously in Marionova's Breaking the Barrier.

Leading here

 * Bowser's Prison: In the throne room, jump through the pipe.
 * Crimson Hallway: In the maze, defeat the Big Boo and jump into its cage.
 * Dead Village: Enter the "molehill".
 * Vanilla Upstairs: Go through the key door.

Additionally, a death results in warping to this area by default (with the exception of some unique cases, like the Balcony).

Leading away

 * Bob-omb Test Site: In the hallway central room, go through the door with the number 3 on it.
 * Big Boo's Haunted Forest: In the junction room, go through the double door to the left of the clock, then through the door with the number 1 above it, and into the Boo painting.
 * Crimson Hallway: In the main room, go through the leftmost door with the number 1 on it, and then the pipe at the front. Alternatively, in the junction room, go through the key door with the clock above it, then through the key door in the middle, and defeat the Big Boo at the other side of the mirror and jump into its cage. Finally, in the hallway side room, go into the room with flames, defeat the Big Boo and jump into its cage.
 * Funhouse: In the main room, go through the second single door to the left of the double door with Peach's painting above it, jump down the hole, go through the next double door and then the pipe.
 * Goomba Hills: In the hallway side room, go through the door with the number "2" above it, and then through the painting with the Goombas on it.
 * Grassy Highlands: In the main room, go through the first single door to the left of the double door with Peach's painting above it, and then through the painting of a tower.
 * Plexal Hallway: In the junction room, stand on the brick block that doesn't have a flame on top of it.
 * Vanilla Lobby: In the main room, go through the single door to the right of the key door with Peach's painting above it, and then jump into the pipe. This is interesting due to the fact that it uses one of the Unused Lobby Warps, spawning you on the sun carpet, with 1 life lost. Alternatively, in the hallway side room, jump into the pipe in the room with flames.

Trivia

 * This area has the most warps (23) associated with it in the entire hack.
 * If you have 0 lives, and enter the Vanilla Lobby through the pipe, then instead of getting a game over, you will now have M1 lives. When this is active, dying makes the number go up, and 1 Ups make it go down.
