A photo from open sources
This video appeared on the Internet back in 2011, but a big did not receive distribution. It doesn’t look like a fake, most likely a real person is captured.
As soon as this creature was not called in comments, and an alien and a hybrid of man and dog and the fiend of hell. Rummaging around a bit I managed to find out that this was filmed in India, and this is still a person, a woman with a rare mutation of the legs (or rather knee joints), which somehow adapted to move in that position.
People passing by, apparently accustomed to her sight and do not pay no attention to her, but for the one who saw her for the first time, this can be really scary.
