Is it possible for it to just show up like that?

Poke it and see if it’s squishy or hard

It is indeed squishy

Absolutely not. Please don’t believe it’s actually a turbinaria.

Yes it would be because no way a stint coral would just pop up. So the mystery item would could be like a egg case of some sort or sponge, idk

I have had coral that has died like a plate coral is it possible for it to reappear?

Also, yes, it is possible for a lot of corals to seemingly come back from the dead, but not that fast or drastically.
