"It's just a storage with nothing but old junk lying on the floor. I wonder where the items came from..."
Summary:
The storage is next to the "A Bizarre Building", where there is an underground building which leads to the a black back door, leading to the Underground Storage room. To enter the storage room, the player needs to have a stand that could teleport through walls; an example would be Made in heaven's v move. The storage room also replaces the Tom's Juice Shop, which has been deleted. This Storage is also near the sewers, which is also located in the Underground space. As of today, there is no explanation as to why this room exist, as there is nothing unique included in this room. The only explanation could be for aesthetic purposes, with boxes and a painting between them.
