It doesn’t look like it has ball tips but it’s very small right now too so hard to say. But it definitely comes in & out of the shell. I’ve had the same snails for 2-3 months & I just noticed it, have no idea how it got there.

It's a possible to stay retracted because the snail is moving, around my ball anemones I have few small jelly like clumps one already "hatch"and there come out another one, probably the same way it's attached by the adult ball anemone to the snail shell.
