Tentacles

A tentacle creature with no guidance and no power has to somehow survive all alone within a cave, which it was abandoned in by its cruel and unforgiving creator. How could something as weak, and useless, as a low level tentacle monster survive within a cave that holds no human inhabitants, besides the casual adventurer that goes within it to kill and gain experience? It's simple, really. All it has to do is consume and eat. Consume everything it can find. whether it be the living, the dead, or human lust (Females specifically). And consuming human lust is exactly what it's going to do.
