Forest World is one of the main areas accessible from the Nexus.
The soundtrack for this area is yumepo6.
Features
It is filled with pine trees and white stones (similar to the doorway to the world). There is a white chocolate bar somewhere in this world that transports you to Chocolate World. There is also a hole in one of the white stones that teleports you to a sectioned-off area
with an elevator at the other end. Taking the elevator will then transport you to a similar-looking path, and going to the far-right of that path will lead you into a giant rock formation in the shape of a monster. Occasionally, equipping an effect and interacting with the far end of the monster's jaw will show you where the effect can be found.
Underground
This is a sub area found when you reach a hole with traffic cones and a sign next to it. There should be a gap there that allows you to go down the hole. Underground is basically just a maze where you can find the Lantern effect. When you find it, the area goes dark, so you have to use the lantern to find your way out again. You can also reach the Underground TV Complex from this area by going to the far right and finding the spot with a sign next to it.
Shadow Woman Forest
Somewhere in this world, you will find a sane Shadow Woman. If you chainsaw her, she will become insane and start to chase you. But if you manage to get away from her and go to the Underground area and wait for a few seconds before coming out again, you will find the Shadow Woman Forest. This is simply a darker version of the usual Forest World that is infested with Shadow Women that will transport you to a sectioned-off part of the Underground area. One of the white stones has been transformed into a red blob-like creature with one big eye.
