Mollusca Sugeras

A few days ago, just before I nodded off to sleep, a little something popped up in my G+ feed care of +Jacob Hurst. Thanks for rocking me to sleep with this bad boy: Jacob Hurst's Snail Terror.
I had a really hard time getting the image out of my mind... but it was perfect inspiration for a new Labyrinth Lord monster entry. This is my second snail themed entry. I fear I may have a bit of a hang up on them.

Mollusca Sugeras

Inside this shell a terrible, grinding death awaits.

The sucking snail or hoover snail is an odd and terrible predator. It has a natural camouflage (surprise successful on 7-in-8) which allows it to be passed unnoticed, and lightning fast reflexes for snatching up prey. The snail is capable of a sudden surge of movement once ever other round; it can swiftly move up to 15' and make a biting/engulfing attack against one target (surging bite attack).

Mollusca Sugeras consumes living flesh by inhaling and grinding it under its coarse, plate-like teeth. It lies in wait, camouflaged by the environment, surging forward to engulf its prey and then withdrawing in its shell to feast. Most sucking snails also keep a small lair of some kind nearby to avoid larger predators. 

Smaller varieties of the sucking snail are of little danger to adventurers but small pets, familiars or pixie followers will be ideal snacks for the shelled menace. The greater sugeras is an uncommon sight, but represents a real threat to any that would venture too close. The creature will consume clothing, equipment, weapons, armour and magical items - anything it can get in it’s mouth. Flesh is ground up and consumed and indigestibles are moved through a strange process to reinforce the shell of the Mollusca Sugeras. Those few heroes (fools) that have managed to find and best a sucking snail have found troves of treasure inside the shell. The calcified bits of shell that envelope the trove items take several days to chip off and clean away, but then you are rich!
