Sponge inside hammer skellington

Hi just noticed I have a spong inside hammer skellington similar to the one I have on my rock in picture bellow…. Should I deal with it and how so?

How is a sponge INSIDE of the skeleton? Did you mean that it's growing on the side of hammer coral?
Please post a pic.

No inside of the skellington…. had small holes in it and was fully of micro brittle stars… found a white lump of sponge on the bottom front…. Turned it around and seems to be comming out of other side…..

That’s the hammer
