In recent times there have been 2 cases which are famous for being urban legends. One incident happened on July 23, 2008 called the Montauk Monster and another on July 02 2009 called North Carolina Creatures.
It was sighted on the beach at Montauk, New York by local residents. There were no official explanation about the identity of the creature. Multiple theories were flouted but hardly anything could come to any conclusion. This photograph is indeed one the best in the recent years.
North Carolina Creatures
This was spotted in the sewer system of the North Carolina , USA. It had the highest number of views on you tube with over a million hits. Officials said that it was common for the worms to form and live in bunches especially near the drainage systems. But it certainly had all the ingredients to speculate the presence of the 3rd kind !
