Possible hitchhiker

Hi, I just wanted to see if anyone could help me identify what’s that white thing growing on the side of my hammer coral. There’s also more growing on the rocks in my tank but this one is the biggest one thus far.
Thank you.

Looks like a pineapple sponge. Good filter feeder. Doesn't usually bother corals. Welcome to R2R by the way.
