Handy!

It's basically a monstrosity that governs a hive of fleshy horrors. Outside of the cave are countless small grey rocks, that turn out to be... hands. They wake up when they feel even the slightest disturbance and observe whatever caused it. The hands are rather weak, but can cooperate to capture and kill some weaker enemies. If they deem an enemy too strong, they will not attack unless attacked and will allow them to enter the cave.
Anything they kill is slowly torn apart and gulped down to the main body as nutrition.
The hands serve mostly as an alarm/detection system.
