Graveyard World (墓の世界, Haka no Sekai, Grave World) is one of the main areas accessible directly from the Nexus.
Features
The world contains many tombstones and red, blue and purple monsters dancing around in formations (as well as a green triangle shaped creature with a smiling face darting around quickly). The purple monsters will follow you around. The background music has a "wonky" melody that keeps changing pitch. In older versions, the ground used to be littered with eyeballs and more tombstones but were probably removed because it made the world too cluttered.
There are a number of large, colored suits (hearts, diamonds, clubs and spades) with googly eyes that follow your movements. If you find the heart that's vomiting, you can go through its mouth to get to the Hospital.
If you go into the small gray building here, you'll come to the Weird Room. It's simply a gray room with green and turquoise splatters on the floor and a strange sculpture of the same color scheme. It also houses nine of the purple monsters. If you chainsaw the sculpture, the background music becomes more high pitched and ominous. The monsters will gather around you and the screen will turn red. After a transition, both the monsters and the sculpture will be gone and you won't be able to exit.
If you manage to leave the room after chainsawing the sculpture, and before being caught by one of the monsters inside, a bunch of the purple monsters will form around you in a square and one will get you.
The soundtrack is ym2-19_kuruwasiimonohahaieguru (Main Area) and pipoq (Weird Room).
