Films: The Crater Lake Monster (1977)
Height/Weight: Twice that of an average automobile.
Summary: Nessie's not the only lake monster around. There are other plesiosaur-esque creatures lurking in the world’s millions of bodies of water. Take for instance this burly beast from the great northwest.
History: Apparently, this guy's ancestors have been coming into conflict with primitive man for years at Crater Lake, California. But that all stopped at some point. At least, until a hot meteor crashed into the lake recently, warming it up considerably. Now this plesiosaur has come out of hiding, and there's plenty of fools to snack on.
Notable Kills: Nothing special.
Final Fate: The beast is eventually confronted by a bulldozer, which impales it enough for it to bleed out and die.
Weakness: Anything conventional.
Scariness Factor: 4-A particularly nasty Nessie clone, this creature has some good stop motion and a voracious appetite going for it. As for the puppets used for close-ups, they can range (depending on the light used) from amateurish to downright ominous and terrifying.
Trivia: -Crater Lake is an actual place, but there's another all the way in Oregon. What exactly was wrong with Oregon, mister director?
-An American lake monster similar to this one is Champ, a plesiosaur said to be living in Lake Champlain, Vermont.
