Homebrew Cubeling (Slime) Species Details

Whether it be reproduction with an ooze, a curse from a god having a lark, or a natural evolution of the ooze-based species of the wilds, Cubelings exist as intelligent humanoid beings whose bodies can be as amorphous or rigid as they desire because it is made entirely of slime. Incredibly, their bodies are not only malleable but elastic to a point, and they possess no internal organs, instead relying rather on a kind of unified cellular structure that only a biology driven by enchantment would explain.

As Cubelings have a non-traditional origin, there are very few instances of a community of them gathering in one place. More commonly, one can find a lone Cubeling, or perhaps a pair, wandering through town or living a humble life in the wilds. Oddly, Cubelings do not often seek their kin. Rather, they seem to be content with companionship from any who are willing to have them despite their bizarre nature. In turn, Cubelings tend to hold dear their found family rather than blood relations. There are exceptions to this, for a few known villages of Cubelings exist. Primarily found within the underdark, most of these villages are peaceful affairs where Cubelings live their lives farming whatever they fancy for sustenance (such as mushrooms). However, a few conclaves exist of Cubelings who have fallen to the feral nature of the underdark’s more dangerous oozes.
