Sewer blobs of North Carolina

Everyone is sending me this video of a strange pulsing blob found in a North Carolina sewer inspection. It is officially creepy and disgusting, and someone from the SciFi channel is racing to make creature feature about it right now, I’m sure.

I have no idea what it is, but the explanations that it is a colony of either tubifex worms or bryozoans sounds reasonable. I want to see a sample of that thing put under a microscope.

You are now free to make jokes about <despised NC figure>’s colonoscopy exam in the comments.

The best explanation so far is from Deep Sea News: they’re almost certainly tubifex worms, and they have a comparison video to demonstrate it.
