Ok , I was getting into this until I did google search. ( that is where I found pic of seal , some " lochness site " , seals are known to travel over 30 miles up rivers ) .... Anyway , this is false.Just check the site for the movie.The clip there even shows a guy fall in the water and they start shooting at it....Here is some of text , and heck..here is link...But , yes , there are seals that occasionally go up the loch

..but probly inner tube here.
The really important thing to remember is that Incident at Loch Ness is a faux documentary, a hilarious account of the making of a movie entitled Enigma at Loch Ness. Actually, it's a fake documentary of Werner Herzog by John Bailey
