It is usually found attached to the walls of caves. It can be either picked up or harvested for Gel Sack Spores by using a Knife. Both items can then be planted in an Exterior Growbed.

The Gel Sack is hemispheric in shape and has a blackish green surface covered with thick, twisted ridges. Randomly scattered across its surface are protruding, bioluminescent purple spots.
