Abandoned Chinatown (オリエンタル, Orientaru, Oriental) is a small area accessible from the Forest Carnival by tearing a hole in the curtain between the chairs in the cat-faced rug room.
From the entry railing, this area brings you into an old oriental town, mostly devoid of any human life. Blue flowers surround the walls, blowing in the empty breeze. The corridor leading out to the left is locked, and there is only one enterable building in this area, the Witch's House (魔女の家, Majo no ie, House of the Witch), in the top-left of the area.
The first floor is filled with beakers and bottles, and a large rug of a skeleton carrying a scythe. The second floor is home to the town's only resident, a tall girl with dark blue hair, wearing a kimono.
Another multi-story building is accessible from the Laboratory's cave system via a spinning black object resembling a person.
Nothing of exact interest is found in this area yet, except the NPC.
