Post ID: White cottony blob under live rock.

I recently found this bean sized cottony white/grey dome with some spikes sticking out on the tip under a piece of live rock. Just trying to figure out what it is.

I have Blue Spot Goby, multiple Green Chromis, Basslets, Clownfish, Firefish, Damsel fish... With Cryptocaryon.
Turbo, Nassarius and fighting conch snails.
2 Cleaner shrimp and an assortment of red leg, scarlet and blue leg hermits.

There are some corals like frogspawn, wall hammer, zoanthids, favia, and a scoly.

What could it be or what other information is needed?

I did not notice any spider webs attached or close by.

Judging from google images it does appear to be a harmless pineapple sponge. Thanks!
