The goldworm is fully multicellular and gained a moutjh and an aerostatic skeleton using its helium. Like its cousin the piss sky bush it has spores now but because it is fauna it's broadcast spawning instead, it comes out its back end in liquid form and looks like piss. It floats around eating up all the sky c ells with internal filters derived from flagella. it is actually radially symmetric.
