The Dense Woods is a set of deeper dream worlds in Yume Nikki.
Features
The Dense Woods is a large forested area with a straight road running through it and clearings in the trees in which several warps can be found. The area is also notable for containing the Jellyfish NPCs, who appear during the game's ending.
Worlds
Dense Woods A
Dense Woods A is a rainy area largely made up of conical trees, much like the ones found in Forest World. A straight road also runs directly through this area. It is accessed by entering a pink stairway found in Puddle World.
Upon entering this world, the player will find one of three vending machines found throughout the dream world. By traveling along the road, a single Jellyfish can be found that will stop the area from looping if Madotsuki interacts with it and then heads east. This will lead to the Infinite Road, a road that infinitely loops when traveling east and contains the Floyag. If the player goes west instead of east on the Infinite Road, they will end up in Dense Woods B.
Dense Woods B
Dense Woods B contains both a continuation of the road found in Dense Woods A as well as several forest clearings that will lead to other worlds. Unlike Dense Woods A, it does not naturally rain in this area and the trees are rounded instead of conical.
When entering from the Infinite Road, the player can continue west until they are blocked off by some traffic cones. A corpse known as Shitai-san can be found here, which will give the Stoplight effect upon interaction. Near the connection to the Infinite Road is also a short clearing path that leads to a manhole which will open to reveal a red tentacle if the Infinite Road has been looped through at least two times. This tentacle can be interacted with to reach Manhole-sama and the White Desert Mountain Ring.
Some additional clearings in Dense Woods B can be accessed through a manhole found in the Mall and a portal found in Hell. The manhole will lead to a short trail containing a Frog (who can be interacted with to gain the Frog effect) and a second Jellyfish who can be interacted with for a one-way connection to the Teleport Maze. The portal will lead to a dark, winding path filled with Isee known as the Dark Woods. This path can be more easily navigated with the Lamp effect and will lead to the Traincar.
