ID Creatures in Overflow. Maybe PODs?

[saxplaya]

Just looking to verify identity of these things before I go sucking them all out.
Wondering if they are various types of PODs or spiral worms or none of the above.

Thanks!

I see some pineapple sponges which are good. I don't see anything to worry about in there that you would want to remove.

Squibs and sponges or pods
