Hitchhiker coral/ no darn clue

So this was attached to a frag of zoas I got today, and I have no earthly idea what it is. It doesn’t move for sure, but it does glow green on top.

I have attached several pictures, one is of the “foot or base so to speak”

Almost looks like the base of a toadstool or leather of some sort with a graboid covered in warts coming out in three places

Bump, anyone?
