This article is about the sapient alien race featured in the movie Signs, directed by M. Night Shyamalan. They are very athletic, being able to jump up to the roof of a farmhouse that is about ten feet off the ground. Their skin changes colors, giving them a camouflage ability- which is how they remain unseen throughout most of the movie. They also have a spike that protrudes from their wrists that expels poisonous gas. Water is their weakness- shown at the end of the movie when the one in the farmhouse falls backwards into a piece of furniture, toppling a glass of water on top of it, causing the water to drip on it. The water seems to "burn" the alien and cause it great amounts of pain.
