Ahuizotl

'''The Ahuizotl is a mythical beast from Aztec mythology. Legend says the monster looks like dog and has a huge tail with a hand on the end. It says that the Ahuizotl will wait in the river for a victim and start wailing like a lost child or frightened woman. Soon, someone will come over to help. The Ahuizotl will strangle it's prey with the tail-hand, tear out the teeth, nails, and eyes and eat those, and toss the lifeless body into the river and restart it's wailing.'''
