Need help identifying this coral like hitchhicker

[reefo420]

i haven't added anything to my tank in a few months but this just started showing for the first time
any idea on what it could be?

Looks like some hitchhiking clove polyps. Or an old colony that was dormant from die off coming back.

I never had any corals in that rock, I have bought a few crazy rocks from indonesia that had a lot of hitchhickers over the past few months that i was able to get rid of, but I've never had this type of papaya before, I've had 4 heads of a purple/green clove polyp that doesn't look similliar to this, does the color change over time? because my pistol shrimp killed that a few months ago somewhere else in the tank and i belive it died
