Huh, I hadn’t considered that. I remember seeing an animation with one once, but it might have been in Blender rather than SFM.

They’re called Hanar.
I feel like I’ve seen SFM models somewhere, but they might’ve been lost when digitalero went down at some point.
Or else it was just tentacle models that looked like hanar tentacles

@shittyhorsey has made some hanar stuff in the past though I don’t know where he got the model from. 

There’s an okay Hanar model here and I somehow have another model that I can’t find the source for. When I get back to my computer I can see about packaging it up.

I’ve started making hanar tentacle porn so many times….

Here is the one I have.  It ain’t great.  The tentacles don’t really bend all that well.
