Drooping Stingers

Hanging stingers are a life form appearing in caves. Hanging from the ceiling they are waiting for prey to be caughty by their stinger.

Looking like a hybrid between a sea anemone and a Jellyfish they are attached to rock, waiting for prey to be entangled in their tentacles.

Behavior
Their behavior was fleshed out on this trello card.

A few key points are:
 * Damages anything live that touches it (Poison damage).
 * Target gets set as GameFlagState.Poisoned for 5 seconds (GameFlag.Set(obj, GameFlag.Poisoned, 5)
 * While poisoned, loop poison damage sound for creature, and take damage over time.
 * Smaller variants do less damage for less time (-50%), larger variants do more damage for a longer time (+50%).
 * When emissive lights on Stinger are glowing, that means the Stinger is active. After it stings a target, it becomes stops glowing for 5 to 10 seconds (random). Then it fades the glow back up over 1 second, after which time it is active again. Alternatively, the stingers could retract a bit instead of change their glow if that’s much easier.
