ID a hitchhiker please

This small soft coral came on the same rock as my new Pseudopterogorgia. Could any of you please help me figure out what it is?

I have no idea what that is, but all those polyps look like little hands, reaching, grabbing . . .

You need to market that thing to someone who does Hollywood horror!

Looks like a species of colt coral to me, mainly harmless but your pseudo would be happier in the long run if he were removed and placed on his own rock.
