Strange creature in my bathroom

Go on google type up: Sewer rat and one of the first few pictures should be an albino HUGE rat. It could be something like that, similar. (Sorry I couldn't put up a link, my computer is acting up on me again.)
And I remember as a child I used to do the 'Blood Mary' rituals, and I was so afraid that my sub-conscious mind playde tricks on me and I was starting to actually see strange stuff in my mirror, all because of fear. So that is another solution as someone posted above.

I thought it was a rat, too. Or may be it was some sort of ferret? that's really far fetched, though.

Okay as you can see there are several viable ways a small critter like a ratty could get into the drain. There is a vent, usually slightly above the foundation on the exterior of the house...over time this vent can rot inside and the valve can become stuck open allowing access to intruder critters. It's a bit of a drop...usually about 4 to 6 feet and it's likely slick with mildew and whatnot, making it impossible for a critter to get out.

There is also another valve under the cement that often becomes stuck open.

Chances are it was a little ratty who either came in from the main sewage line during wet weather (the water levels rise and rats are great swimmers) or fell in from ground level.

More likely it was not drinking the water but trying to breath. The effect of gravity with the push of air and water makes the pipes a bit shallow airwise and it was likely having a hard time breathing.

The little critter more than likely had been holed up in one of the redundant pipes (the basins) used for overflow and to limit backups. And when the water started running it started getting hard to breath...so it would naturally go towards the flow of air...even though it meant getting wet and being trapped.

Not to worry though. Ratty likely died in the pipes and his little decomposed corpse would be (hopefully) washed away with the sewage water.

side note...rats will lose their fur quite dramatically if under severe stress...like being in a drain. My bet is a rat got in but couldn't get out and was just gasping for air at the drain cover.

Poor ratty. You might wanna snake the drain BTW...make sure the ratty corpse isn't clogging things up, and to make sure your backwater valve isn't stuck open allowing for any other critter to make it into the sub plumbing of your house. Also check the plumbing vent on the outside...make sure the cover is intact or the drain screen is on. You can snake that one too to make sure the valve isn't blocked.

its an albino graboid!

but really it was prob a rat, or just a lizard, its pretty warm down in the sewers even during winter

Justgeneric has it right I believe. In my municipality we have no screens on the roof vents and all kinds of animals can get in them. Sometimes plumbers group many vents together and have a larger vent, maybe 3" in diameter sticking out the roof which is quite large enough for even a cat.
Also vents are designed so that any water that gets in them flows back to the fixture they serve, i.e. your shower drain.

i think i saw this in a grade c horror movie but the title escapes me.perhaps it would have been best to have called rotor-rooter!

Interesting the teeth and jaws look reptilian but the drain obscures it I say it maight be a rat or if not then maybe a small lizrad or crocidilian

I am NOT so sure it's a rat, telling by the drawing.
