The Mall or Department Store is the popular name of one area in Yume Nikki. It is a black-floored, purple-walled complex. It is full of people, but when interacted with, they only deform slightly and make odd rattling/hissing noises.
Its layout is quite strange. It has several pathways, rather like a maze, with walls facing diagonally. There is a second floor, but what is on it changes depending on how you enter it.
One room - located to the far right of the map - is a small room with a large pool of red liquid (believed to be blood) on its right side. Two posters are on the wall, and it is populated only by a minute sort of pillar with limbs and eyes. When it is interacted with, it tips over, spilling blood onto the ground out of a hole in its head. This character is often referred to as "Tokuto-kun" or just "Tokuto".
Another room, located in the bottom left of the map, houses a harmless, lunatic Toriningen sitting behind a counter and an oddly shaped character chilling on a sofa. This second character frowns whenever the cat effect is used and even sneezes if you stay long enough inside the room.
Effects
The flute effect is located here, in a room in the lower-left of the mall.
Connections
The Mall can be accessed from the Graffiti World or by entering the elevator after falling asleep in a dream bed.
Part of the Dense Woods can be accessed from the basement. Talking to the creature there will transport you to a Teleport Maze, which leads to an FC world that connects to the White Desert.
