What is your yêu thích cryptid hoặc urban legend?

Personally I am fond of Shirime a Japanese demon who has an eye for a bumhole. Apparently this is the most wildly told legend; "Long ago, a samurai was walking at night down the road to Kyōto, when he heard someone calling out for him to wait. "Who's there?!" he asked nervously, only to turn around and find a man stripping off his clothes and pointing his bare buttocks at the flabbergasted traveler. A huge glittering eye then opened up where the strange man's anus should have been." That's it, that's what Shirime does.

I also like Nessie.
