WTF is that??

A couple of days ago, when on my way to toilet, I was attracted by this unknown thingy in the kitchen. I thought it just a normal worm that was crawling on the floor. As I walked closer and looked carefully...this is how it looked..

Can anyone tell me wtf is that? It has 2 eyes and quite sticky. Is it a snail without shell??

Any idea??

So I got no choice, I took a slipper and pushed it to the toilet bowl. When the slipper touched it, it rolled itself and become an unknown shape. Look at the photo, I can't even find its eyes. Look like shit?? In the end, it just gone with the water lol
