A wild video from South Korea shows the moment when a fisherman spotted a mysterious creature that suddenly appeared in the water and swam toward him while he stood on the shore. The strange sighting reportedly occurred at the Han River in Seoul last month. Footage of the remarkable moment (seen above) was posted on YouTube by the channel Jungdam Story, which normally features fairly mundane videos wherein its host visits various fishing spots around the country. However, on this occasion, something seemingly extraordinary unfolded that left the man fleeing the scene.

In the video, as the host sits at the shore of the river with his lines cast, he suddenly sees something unusual out on the water. "What is that? I'm scared," he exclaims in astonishment before observing that "it's moving toward me." The oddity's approach understandably unsettles the fisherman, who jumps out of his chair and shines a flashlight at the creature. However, the illumination failed to provide an answer as to the nature of the 'monster' that he estimated was around 13 to 16 feet long and boasted a thick body.

Amazingly, the fisherman indicated that the creature lingered in the water for around 20 minutes and, at various points, there appeared to be two mysterious 'monsters' out on the river. Looking back on the bewildering sighting, the man marveled that "I've been fishing for decades, but I've never seen anything like this before." Since being posted online, Jungdam Story's video has gone viral in South Korea and sparked considerable debate as to what appeared in the river that night. What do you make of the peculiar footage?
