1. Land mollusks: herds of great-horned slugs, flocks of aero-snails with fuselage-like shells, gas jet propulsion
2. Mice, moles, voles: from tiny to giant, cute, non-aggressive, scamper at impossible speeds and reproduce like nobody's business
3. Huge, revolting, acid-vomiting flightless house flies
4. Ambulating land plecostomus
5. Dungeon goats with mutations like iron teeth, ten stomachs, rhino-like armor
6. Giant grazing lizards: uninterested in melee combat, skittish, easily provoked into lethal stampede
7. Lower dungeon apes: stalactite dwelling sub-monkeys, shrieking, bug-eyed prosimians
8. Grazing ooze: nearly motionless when feeding, careless adventurers could blunder right into one
9. Dungeon fairies: build massive spiked hives, process food source into honey-like product
10. Schools of shrimp-like crustaceans swarming about the walls, floors and ceilings, rudimentary collective intelligence
11. Toddling, morbidly obese flightless bats with shrunken vestigial wings and defensive chaos-stench
12. Elusive herds of black and gray camouflaged miniature zebras, will kick like hell with razor-edged hoofs if cornered, wicked mohawk manes indicate position in hierarchy
