Broodling in a Bottle

One of the ghastly critters recently discovered swarming in tunnels under Boston. According to one Paddy McGinty, they make amusing pets. According to anybody still actually sane, they're horrifying abominations with a stomach-turning, sanity-blasting life cycle.

( a quick photoshop to use as a prop in a recent Call of Cthulhu game - The Pale God. The critter in question is one of Eihort's Brood )
