The Cloud World (aka "The Isometric Pathway") is a connecting area with a tiling path and constant rain. Off in the background are IV drips and heart monitors, as well as unreachable beds and what appears to be blood splatters.
The entrance to the pathway can be found by touching the floating objects on the Apartment roofs. The entrance from here leads to a fork in the path, and each path takes to you a different area.
The right path contains two active Kaibutsu, so bringing the Ghost effect would be very wise.
- Apartments (by touching the floating grey cubes)
- Famicom World (by going left at the fork and touching the grate in the middle of the bed circle)
