Shambling mounds are intelligent, carnivorous plant creatures, though they appear to be rotting heaps of vegetation.
Shambling mounds are usually about six feet tall, with an eight foot girth, when they stand erect. Most weigh around 3,800 pounds. Their brains and sensory organs are located in their upper regions. In their natural environment, shambling mounds are almost invisible. They can move through water easily, and have been known to creep into camps in their range at night to attack. Stories tell of shambling mounds moving about in electrical storms without flinching from the frequent lightning strikes, even direct strikes.
