Wow what a strange sight! I wouldn't expect to see that, especially there, where it looks like there is water all around for quite some distance. I guess they are great swimmers. I wonder what makes them swim such a distance? Mabye the spot where this guy was trying to live was a bit crowded, and he's searching for somewhere with less company and more fresh green grass.
I have as short video of it somewhere I will post when I get better at the dtube conversion process..
