Forest World is a large scrolling world filled with pine trees and large white stones. There are also a few streetlamps scattered throughout the area.
From the entrance, directly to the northeast is a doorway in a large white stone that will take you to The Monster's Jaw.
To the northwest of the entrance a large hole in the ground can be found sectioned off with traffic cones and a yellow sign. Urotsuki can walk past the cones under the treeline and enter the hole, which will take her to the Underground Caves.
To the east of the entrance is a white chocolate bar that will take you to Chocolate World if interacted with.
The Underground is a winding cave system lit by small lamps hanging from the walls. Not far from the entrance there is a small lantern on the ground that will give you the Lantern effect if you interact with it, but once you have the effect all the lamps in the cave will turn off, making the area extremely dark and forcing Urotsuki to find her way out using the effect.
Much deeper inside the cave is an exit with a sign next to it, leading to the Underground TV Complex.
Shadow Woman ForestEdit
To the southeast of the entrance a sane Shadow Woman can be found wandering around. If you chainsaw her, she will turn dark and start chasing you.
If you run away from her and hide in the Underground area and wait for a few seconds before coming out again, you will come back out into the Shadow Woman Forest, a dark red version of the usual Forest World infested with Shadow Women that will transport you to a sectioned-off part of the Underground area if they catch you.
All the exits from this area are inaccessible, and the white stone that acted as a portal back to the Nexus has been transformed into a red blob-like creature with one big eye.
If you chainsaw the large red creature it will groan and large cracks will appear all over its body. Doing this will make the door to chocolate world reappear and allow Urotsuki to escape.
The Monster's JawEdit
The Monster's Jaw (高台, Kōdai, Observatory) is an area accessible through a doorway in the large white stone just northeast of the nexus entrance. The doorway takes you through a sectioned off corridor of Tapir-San's Place, with an elevator that will take you to the next floor.
Leaving the corridor at the top of the elevator will place you in the jaw of a large monster which appears to be made out of stone. Interacting with the edge of the mouth with certain effects equipped will display a small scene.
