Red sponge thingie freebie?!

[najer]

I have been buying a lot of softies recently, this is on the base rock of a green sinularia!
I am going to look but thought I'd ask here first if someone can identify it please?
I love the little face. ;)

Hello,

Gotta love free. I’m not thinking sponge, but I am thinking alien so I have no idea.

Maybe an anemone?
