Angrenifs are shapeless blobs of living matter that can be found in the deserts of the world. They are extremely resilient and can survive for years without water or food, instead drawing their energy from the heat of the desert. When an angrenif is in direct sunlight, it will begin to move faster and morph to grow larger; but when it is in the shade, it will slow down and begin to shrink. Their typical lifespan is about one hundred years.
