Pucker Kelp thrives in large colonies near underground lakes and rivers within the Gloom. These impressive kelp can reach heights of up to 8 feet, adorned with bulbous amber orbs along their flanks. These orbs can be harvested and crafted into lamps, providing a soft, ambient light. Additionally, the juice within the kelp is popular in the making of sour candies, producing an intensely sour taste believed to have evolved as a deterrent for predators.

The glowing bulbs of Pucker Kelp are the result of unique chemical processes within the plant, creating natural lanterns that illuminate the pitch-black environment of the Gloom. These large structures serve as shelters and bridges for local animals, offering safe passage and refuge. The light emitted by the bulbs helps various creatures navigate the darkness without attracting the attention of Tenebre's servants. Pucker Kelp is thus a vital and versatile resource in the Gloom, contributing to the survival of both flora and fauna in this shadowy realm.
