The Crab Demon is a minor character on Adventure Time who appears in the episode "Red Starved". He and Paris were planning to turn a city under the Desert Lands into sand and reanimate its inhabitants to conquer his homeland at the center of the planet, but this plan fails because he zones out for long enough for his partner to die. His third eye can shine a ray of light that turns anything it touches (except gems) to sand. Finn encounters him while looking for something red for Marceline to eat.
Appearance[]
His skin is light green, and he has a darker green shell on his back. There is a third eye on his forehead. The sclera of the third eye is pink, and the iris is red. However, since the Crab Demon was seen from Finn's colorblind perspective at the time, there is a good chance that his third eye is actually two shades of green.
