Bulb Bush

It is currently unknown wether the Koosh Bush is Fauna or Flora - although the name indicates that it is indeed a plant. It is found in the Biome called Koosh Zone.

Artwork shows that divers could potentially interact with it. In current builds the  Koosh Bush can be harvested for Koosh Chunk  with a Knife.

The Koosh Bush is Bioluminiscent.
