Bandersnatch with claws that grab

The bandersnatch as I see it, being a beasty that isn't a beastial creature but a stalking hunter that eats children and men.

The flesh of their victums is allowed to petrify in the rather damp insides of the bandersnatch, allowing for the creature to easily ingest the necrotic flesh and absoarb nutrients from the now rank flesh. These beings do have a mouth under the masklike facial plate, although they have no teeth and their stomach acid is weak, their claws can easily puncture heavy plate armor, making trees and some rocks useless to hide behind.

On further note a sleeping bandersnatch, after a meal always has a peculiar sickly sweet scent upon it's body, and can be host to carrior wyrm larva with whome these beasts happen to be supporting for various reasons.
