Beta Lobby B

Beta Lobby B is an area in B3313.

Description
The area is traversed similarly to the vanilla Super Mario 64 castle lobby. All numbered doors 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.

Origins
The main room's model is taken directly from the Shoshinkai beta build 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.

Trivia

 * The strange noise that plays sometimes when entering doors (Most notably the door to Plexal Upstairs) is a reference to this particular beta footage.
