SERIOUSLY. THIS ISN'T RIGHT.

i HAD TO STAND UP OFF THE TOILET TO MAKE SURE MY ASS WASN'T ABOUT TO BE BIT OFF BY A FUCKING PTERODACTYLE OR SOMETHING

Have you tried tossing in a cherry bomb? I can't see how that would be a bad idea in any way.

Its are bubbles circulating, It does sound like something lapping about though doesn't it.

Are we sure it's not just a long-lost turd, one who escaped "the Flush" by entering the Central Heating System and has been floating around your pipes, trying to find its way back home to that sweet warm arsehole it once left so many moons ago....

The "Dreamcatcher" by Stephen King may help you in this case, I think.

This. There should be some sort of valve thingy, usually at a corner of a pipe or someting. Find the highest one you can find (not necessarily near where you hear the sounds). When the radiator is cold, open it slightly (mine has a special key for it, but it's just a square thing you need to turn), while holding a microfiber towel or something to the opening to soak up the liquid that comes out. You'll hear some sputtering at first, and when that stops, all the air is come out and you can close the valve again.

If instead of sputtering you hear growling, a tentacle comes out, some hairy insect leg or a corrosive biting gelatinous substance, then RUN. Or maybe close the valve first and then run.

If the stuff that comes out has a really foul stench, that's nothing to worry about, radiator liquid smells horrible, because it's closed off from most air all the time. It can also be dark grey or even black in colour because when they installed the piping system, a lot of fine metal filings/dust ended up inside the pipes.

I bet it's the lady in the radiator from Eraserhead.

It could be a baby crocodile.  I've heard those live in sewers in America, growing to giant sizes and eating the unwary.  It would be irresponsible not to speculate.
