After some piss plants ended up stranded on Kamm, they found themselves in an environment with ample sources of food. Despite hailing from a lineage of photosynthetic organisms, these piss plants were able to extract enough nutrients from the surrounding flora and fauna that they no longer needed photosynthesis, becoming the pissaprobes.

Pissaprobes mainly differ from their ancestors in that they are no longer capable of photosynthesis, losing their piss-colored pigment as a result. Instead of simply landing on the ground and using their roots to plant themselves, they now land on the corpses of large flora and fauna (such as piss plants and clonguses). From here, they plant their roots into or near the dead material, spreading them throughout the cadaver or log in a similar manner to mycelia. When there is nothing left for a pissaprobe to consume, it warms its wings up and gets ready for relocation. However, the roots of a pissaprobe are often far too long to pull out of the decomposed material, so they simply detach the roots instead by “pinching” them off via cytokinesis. Their skeletons are more developed, allowing more attachment points for the actin fibers that help them fly.

A single pissaprobe can birth many offspring in its lifetime, which is usually many years long due to their reliable feeding strategy. These offspring detach from the parent at only half a centimeter long, flying up into the air to hastily search for the nearest rotting organic matter.
