SPOILER!!! I have been trying to figure out what the name of this movie for YEARS! This one and the Trilogy of Terror episode with the tiki-doll scared me to death as a kid. I totally remember the "mud monster" (that's what I called it) using the ground to regenerate. I also remember the hand getting cut off in the door-frame. I remember the hand gets cut off and it somehow makes it way to the basement. They go into the the basement later to get something and the hand (which is on one of the steps) grabs one of them and the struggle. A shelf gets knocked over and a bag/jar of salt is spilled on the hand and it catches fire. You then hear the creature screaming from somewhere on the island because it can feel its hand on fire. They then figure out that salt will kill the creature. The decide to use of themselves as bait to lure the creature into chasing them. The tie a rope between two trees and during the chase the creature is tripped into the salt-water and is destroyed. Wild movie...
