Shambling mounds, or shamblers, appear to be heaps of rotting vegetation. They are actually intelligent plants, with a roughly humanoid shape and a brain-like control center in the "chest."
The carnivorous shambler is almost totally silent and invisible in its natural surroundings, often catching opponents flat-footed. It may lie partially submerged in a shallow bog, waiting patiently for some creature to walk. onto it. Shamblers move easily through water as well, and they have been known to sneak into the camps of unsuspecting travelers at night.
Adventurers tell stories of shamblers moving about during intense electrical storms without so much as flinching from direct lightning strikes.
A shambler's lower half has an 8-foot girth, tapering to about 2 feet at its "head."
