The Fantasy Badlands is an area accessible from a flashing heart-shaped plant in the Seabed.
The Fantasy Badlands is a set of green, glass-like formations that resemble islands. The area is traversed by flashing, green plants that teleport Sometsuki around the islands.
The area is largely linear, consisting of two islands that can be walked on and an open space with many butterfly NPCs flying around. By finding and following the plants around the world, the player will eventually end up on an island with a cubic house with plant-like markings on it which contains the Schoolgirl's Room.
