    What are these things growing on my rocks? They have like two tube type holes on top...(sorry they're not very clear!!)

    Oh and this, is it a sponge or something? Why does it pop up? It's no longer there.

    I can't tell by your pics but when something has two tubelike holes, the first thing that comes to my mind is a tunicate of some sort.
