not have enough men to cover the 48 miles of shoreline. Two teenagers, previously seen in the episode "War of the Coprophages", head to the lake to lick toads; while experimenting, a diver friend of theirs is suddenly attacked underwater and his severed head floats to the surface. Scully, still skeptical about Big Blue being the killer, thinks that a boat propeller was responsible. A photographer named Ansel is also attacked just as he was frantically taking pictures of the creature. After falling into the lake and feeling something in the water, the Sheriff orders the lake closed. While Mulder looks at Ansel's photographs later that night, Scully takes Queequeg for a walk; the dog, sensing something in the nearby woods, ends up running off and disappearing (yelping is heard), becoming the latest victim of the attacks and leaving Scully saddened. Mulder realizes that the Big Blue sightings have been occurring closer and closer to shore. Mulder and Scully rent a boat and head out onto the lake; their boat is quickly struck by something and sinks. The two find a large rock to climb up on and talk for a while about Mulder's quest to catch Big Blue, and the book Moby-Dick. When Dr. Farraday walks by the two realize they were close to shore all along. Mulder thinks the drop in the frog supply has caused Big Blue to move closer to shore and seek alternative food sources. Farraday is soon attacked but manages to make it out alive. Mulder chases the attacker into the woods and fires at it, revealing it to be an alligator. Mulder is disappointed that the killer ended up being an alligator and not Big Blue. As the agents leave, Big Blue swims nearby in the lake, unnoticed.
