Graveyard World is one of the main areas accessible from the Nexus.
Features
The world contains many tombstones with red, blue and purple monsters dancing around. The background music has a "wonky" melody that keeps changing pitch.
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 to the cube building, you'll come to the Weird Room. It's simply a grey room with green and turquoise splatters on the floor and a strange sculpture of the same color scheme. Sometimes if you come out of the room again, 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).
