Rot grubs are occasionally found in heaps of offal || shit.
They are rarely found in ceilings, walls, or floors.

Burrow into flesh: These small creatures will viciously
burrow into any living flesh which touches them, for they greatly enjoy
such fare to dine upon. The victim must immediately apply flame to the
wound (1-6 HP damage per application) or have a cure disease
spell cast upon him. Otherwise, the rot grubs will burrow to the heart and
kill their host in 1-3 turns.

Those that are not truly proprietary are:

rot grub--based on a common insect, but not very popular
giant leech--similar to an LA game blindworm
thoul--a critter never detailed in and form of the D&D game and which I have included in the monsters found in the CZ dungeons already
lungs are already covered as dragons in the LA game, with

I guess I'll work up the thoul for the LA game critters then
