Life form stuck in drain pipe!

This guy is blocking my drain pipe. I am not 100% sure what it is. It for sure has spots on it, and it is firm and stuck to the pipe very well.

I did see turbo snails nearby but they were small by comparison.

is a video of it.

How big is your drain pipe? Just trying to figure out size comparison.

Whatever it is, it's cool and creepy at the same time!

Edit: spelling is hard

That is an inch ID.

Hard to tell but it looks like a chiton of some kind.
