Any idea what this weird zoanthid colony is?

There was a big colony on a live rock at my LFS. I didn't buy them so I can't give much more detail than the pics show, other than they seemed really bouncy and balloon-like. They look like what would come out if you put a palythoa, an anemone and oyster mushrooms in a teleporter together.

Those look like zaos that are under extremely low light, stretching up to get what little they can.
