Green Button Polyp - Inflamation?

[scoger]

Hey All. I have a little colony of Green Button Polyps (I think, I'm still pretty new). There seems to be an inflamed one that is growing a pod or something. Circled below. It's pretty solid and has me concerned as this colony had bubble algae growing on it at some point. I removed the bubble carefully, but this has me worried it's going to burst and cuase a real BIG problem. Anyone seen this before and or should I be worried/remove carefully?

Are you sure that's not a little pineapple sponge growing among the zoas? Hard to see in picture and not sure about the red color, but that was my first thought.

That looks like a tunicate of some sort. Cool to have.

Better picture (and the red is Cyano that I HATE). Perhaps a pineapple, I had never heard of that before. And I just noticed a new bubble algae. Also, thanks for the ID help!

I would say that is definitely a pineapple sponge now that I see it under whites. I had a bunch in my tank a few months back, but they slowly declined in number. I still have a few in my sump, but I don't see them anymore in my DT. In general, they are not a bad thing to have, but I'm curious if that one will irritate the zoas where it is at.
