Beta Lobby D

Beta Lobby D is an area in B3313.

Description
The area is traversed similarly to the vanilla Super Mario 64 castle lobby. The doors on the left lead to paintings, while the middle doors at the bottom lead to a hallway with another single door at the end of it.

The main room's layout is identical to the other beta lobbies.

From left-to-right the numbered doors are labeled 2, 1, and 3.

Origins
The main room's model is taken directly from The Preservation Project's Spaceworld '95 demo build recreation of Super Mario 64, with some discrepancies in others regarding wall textures, which are also taken from the game's beta or vanilla files, along with the paintings.

The music playing is the "Inside Castle" theme from the vanilla game's OST.

Leading away

 * Snowman's Land (beta): Enter the leftmost door (labeled 2) and then the painting.
 * Bob-omb River: Enter the second door from the left (labeled 1) and then the painting.
 * Castle Grounds: Enter the double door at the back.
 * Beta Lobby B: With 10 stars, press the C-Up button in the middle of the main room and look at the ceiling (similarly to how you would access the wing cap stage in vanilla SM64).

 * Plexal Lobby: Enter the double door at the top.

Trivia

 * Technically, this area isn't separate from the Beta Lobby C, however, a jingle plays when crossing the door that connects the two
 * The mechanic of walking from one lobby to other lobby with some differences originated from one of Greenio's video.
 * The strange noise that plays sometimes when entering doors is a reference to this particular beta footage.
