Challenge Lobby

Challenge Lobby is an area in B3313.

Description
A cylindrical room decked in the Vanilla Lobby's wallpaper with several doors placed across the walls. One of the double doors in the Lobby leads to a small room with a metal door in it. Also present is a rather concerning brick wall. Probably best to forget that wall.

Origins
The area's layout is taken directly from Greenio's videos, such as Epilogue, Promo show and Deeper Cavern.
