Man, FUCK the Montauk Monster.

This is beyond fucked-up. Paraphrasing from Google Translate and my own shitty knowledge of Spanish:

A weird creature has stirred up controversy among the people of Cerro Azul. Some say it could be an alien, others simply believe that is an animal.

Last Saturday four teens playing on Cerro Azul (Jet Blue, literally “blue hill” - like I said, my spanish sucks) encountered this creature exiting a cave behind a waterfall. The teens panicked at the sight of this thing and they began to thrash it with sticks, killing it. Then they tossed it in the water and left the scene.

I have no idea what that thing might be - it most certainly could be a hoax. But if it was real, I feel very sorry for it.
