Almost Microscopic bubble mass on live rock and substrate

[Lllrrr232]

Woke up this morning to see two tiny spaces (maybe about a cubic centemeter) with a mass of hundreds of almost microscopic bubbles that seem to be attached to each other. One mass broke off the live rock and is floating around in the tank. Any idea as to what they may be? (Sorry for the blurry picture. I have to zoom in a lot in order to get them)

Looks like a egg mass maybe?

Appears to be snail eggs.

As of currently i have a turbo snail thats roughly the size of a golf ball, an astrea, a trochus all of which ive had for months and i got a elephant slug/scotus a few days ago. The turbo is by far the most active, and i haven't seen the elephant slug since releasing him into the tank. I'f imagine it was one of those two as the other two aren't too active. Is there a way to tell, a difference in eggs, or behavior i might be able to look for? Thank y'all for the help!
