WP #107 & #111
The Ocean Floor (湖底, Kotei, Lake Bed) is an area accessible from The Docks by entering the submarine.
This area is dark with primarily large rocks as the scenery, and there are isolated pathways Urotsuki can walk on. Traveling downwards from the entrance will lead to a pathway surrounded by hands reaching out of holes. If Urotsuki follows it until the screen fades, the background music will change.
If you aim to travel in a south-easternly direction, Urotsuki will come to a number of strange obstacles, such as a large octopus tentacle, a broken bicycle and a person with a deformed head keeling over. There is a small pathway to the very right which leads to a small area with a puppet theater at the end of the path. If Urotsuki uses the Child or Stretch effects here, you will see depressing images of Urotsuki being shown in the puppet show. Using the Glasses effect will make the "puppets" stare at her with one eye for a few seconds.
At the very end of the area, there is a lone bed (which Urotsuki cannot get into) and two pathways branching off from where it is. If you zoom out of this part of the map, you can see that it somewhat resembles a uterus. At the end of the left pathway (or ovary) is a large egg. Interacting with it sends Urotsuki to a room in the Pyramid Maze where she can get the Child effect. The right pathway leads nowhere.
- One of the paths in this world is impossible to construct; the transitions for when Urotsuki crosses the side of the map, in one section, lead Urotsuki in a figure-eight pattern without ever having her travel both north and south OR crossing over her own path as she must do to create a figure eight. This is true impossible geometry.
