Purple Upstairs

Purple Upstairs is an area in B3313.

Description
The area's layout matches up with the Vanilla Upstairs, with the addition of a front hall leading to the stairs, and most of the warps in the top floor missing. Most of the walls and floors, as the area's name implies, are coloured purple or have the colour in them dominantly.

Origins
The room is likely inspired by a video showcasing the internal castle plexus in what's likely a private ROM hack, which is also the origin of most wall textures, while some of them come from beta versions of Super Mario 64, as well as the vanilla game.

The music playing is the "Haunted House" theme from the same game's OST.

In v1.0, the music playing is a rendition of River Twygz Bed.
