Found egg sack looking thing on live rock.

[themoonlighter]

I found this on a piece of live rock purchased from my lfs. Can anyone help me identify it. It started out as a non-descript whitish sphere, but now it seems to be forming spheres inside the sack. It has been about two weeks since we noticed it. Any help would be appreciated.

Thanks in advance

Leave them submerged and ignore them. Notice the yellow one on the bottom right of the pic........
