The Monster is a semiaquatic humanoid beast, able to breathe and survive in the water. It can travel on land but must return to the lake to keep surviving. It has large eyes, slimy algae covered skin, and its hands are 4 digits.

Its natural environment is a dark, murky lake called, Phantom Lake, in Mukwonago, Wisconsin.

Professor Jackson and Miss Yates are studying the local amphibian life in the lake and along with a group of newly graduated teenagers come across the Monster's markings. The Monster kills several of the teenagers. Only Elizabeth survives and since Professor Jackson served with "Lobo" during the war tells Elizabeth that she's a splitting image of Lobo's late wife.
