Bulb Zone

The Koosh Zone is a unique type of biome in Subnautica.

It shares borders with one of the Mushroom Forests, the Crash Zone, and the Mountains. It also borders the Void.

Description
The Koosh Zone is characterized by small crevices and overhangs in a sandy dune-like area. It is also abundant with small brown algae and a large variety of plants with blueish purple hues, the most notable of which being the  Koosh Bush.

The Koosh Zone is home to certain dangerous fauna. Notable predators, such as Bonesharks and, especially, Ampeels, can be found scattered throughout the '''Koosh Zone. '''Mesmer can also be found to a lesser degree.

Due to its proximity to the Crash Zone, the southern half of the Koosh Zone is subject to radiation. If the player has not repaired the Aurora's drive room, a Radiation Suit is needed to explore the southern region.

There is a cave system located below the Koosh Zone, known as the Koosh Zone Caves. These caves are accessible via any of the three entrances located within the biome. One of the caves links to the Mushroom Forest Caves.

Several  Lava Geyser s can be found in this biome. This, together with the Koosh Zone Caves, suggests a small amount of volcanic activity in the Koosh Zone.

Wreck 3 is located within the Koosh Zone, containing several fragments.
