It looks like a penis with condom on? but is a worm ...

I have no idea what this thing is called. All I know is that it's some kind of a worm or fish life and it looks like a penis. **EDIT** So I did some more research and found out what it is. It's not a fish. It's a worm. A "Fat Innkeeper Worm" to be exact. * penis-looking * thing * fat * innkeeper * worm
