What are these on my zoas?

Any idea what is growing along with my zoas? The top photo is something growing on the bottom and is about the size of a jellybean. The bottom photo has this thing that is maybe the size of a big Rice Krispie, and looks like it has a little fan-like thing sticking out the end.

Did some looking around, I'm willing to bet the fuzzy thing is a pineapple sponge, but the "foot" coming out of it is odd.

The other photo (w/ the zoas), is on the opposite side of the rock as the presumed sponge (the rock is maybe 1/4 to 1/2 inch thick at that point). Could it be another sponge growing through?

You are correct on your ID on both sponges.

Harmless, correct? They don't seem to be bothering the zoas at all...

Yes they don't grow a mat like some other sponges so it shouldn't irritate your zoas
