Grue Cluster

Blue Clusters are a life form belonging to the flora category.

They can be observed running up in spirals on the stalactites at the bottom of the Floater Islands, although not necessarily in unbroken lines. They are also found in Mushroom Forests or caves. They are bioluminescent and give off a particularly bright light, thus making it easier for the player to find their way through cave systems.

At the moment, using the knife on them makes small clusters of them detach from the stalactite and drift towards the ground.

However, given that they have a name that is displayed when looking at them, it is very likely that they will be harvestable in future builds.

Appearence
