Someone created an entire blog devoted to capturing the beast. Literally, the blog is called “capture the beast” and offers up hypotheses for the beast’s origins:
1) the Montauk Monster is a sleestak from Land of the Lost.
2) The Montauk Monster is the skeksis from Dark Crystal.
While I don’t agree with either hypothesis, I do appreciate the reference to Land of the Lost. The site also has a useful poll about where the monster will surface next and a thorough examination of the monster-hunter.
Best of all, I love the blog’s graphics. Someone is quite handy with photoshop…
