It is late in the evening and the town has begun to settle in for the night. From his living room, a man hears a commotion coming from outside; it sounds like frantic chickens. Getting a flashlight, the man goes to the back porch and shines the light in the direction of the chicken pen. The beam catches something strange- something is at one of the chickens. He flips the porch light on and has a Lovecraftian nightmare: there before him stands a bipedal thing with long arms and legs and sharp quills. The light causes it to turn, revealing large red eyes. It hisses and, in a surprising flash of wings, disappears into the night...

A typical account of El Chupacabra, literally "goat sucker", a mysterious entity which has been blamed as the cause of unusual animal deaths; the dead animal is found with no marks except for two puncture wounds to the neck and not a drop of blood in them.

The classic appearance is that of a four-to-five foot tall creature that walks on two legs, has sharp claws and teeth, scaly skin, red, glowing eyes, a row of quills or spines, and wings. Such a creature is believed by some to be simply to outrageous to be anything of flesh and blood, or attribute the attacks to dogs or other known animals, though this does not deter those who claim to have encountered El Chupacabra for themselves.

Alternative reasoning, however, cannot account for the unusual circumstances of the animal deaths...

I tried to make the other wing look folded but I misjudged what I was doing and ended up with fail.
