Grey Semi Transparent Growth

[OfcrReef1]

Hello All,
Noticed this on my live rock about a week ago now it has grown larger. If I had to better describe it I'd say it seems to have a jelly like texture and looks like there is something inside of it.
Could these be some sort of eggs?
Or possibly the beginning growth of a coral?

Any Information is greatly appreciated thanks in advance.

Looks like a tunicate.

Tunicate or sponge, both being reef safe and filter feeding. Tunicate will have an open mouth and occasionally siphons at opening
