Random Underworld Ecosystem Part Three

Sprinkle With Predators

d12
1. Cavern-filling apex ooze: central mass controls seemingly independent oozes that hunt and return w/partially digested offerings
2. Pack hunting giant armored shrews: armadillo-like defensive shells, perpetually famished, relentless hunters, use intimate knowledge of cave layout to encircle prey
3. Colossal blind floating phagocytes: always ravenous due to caloric requirements of anti-gravity organelles
4. Naked flightless birds: super-dense beaks take up most of head, shatter stone with ease, excavate nests in cave walls, "doors" made gluing rubble with saliva, crystal-studded eggs sought after by sorcerers
5. Shark slugs: drop onto prey from walls or ceiling, adhere to prey with sticky slime, massive toothy jaws
6. Giant hairless bears: huge bat-like ears, vestigial eye spots, echolocation, scimitar-sized retractable claws
7. Shambling gourmets: tall, lanky, ghoulish humanoids in kitchen attire with super-refined culinary aesthetic, always seek fresh/interesting stock for their terrible pantries, autocratic rule by 12' tall executive chef
8. Flesh eating giant apes with semi-domesticated captive population of black puddings in ancient crystal vats used for digestive assistance on otherwise inedible prey
9. Vampiric cave anemones: house bodies deep in cave walls, send out mile-long feeding tentacles, anesthetic saliva delays detection by victim
10. Gas jet propelled cave echidnae: launch themselves at prey, barbed spines kill smaller prey on impact, attach to larger beasts for prolonged parasitism
11. Pit pummelers: like bipedal rhinos with disproportionately huge fists and tiny stupid heads, beat prey to pulp then slurp it up with extensible hollow tongues
12. Cave juicers: shelled mollusks with high speed rotary jaws for liquidating even the toughest tissues, powerful lungs create inescapable vacuum effect up to 10 feet from mouth

Note: Predators indicated above should (somehow!) be adapted as necessary by the DM to suit the peculiarities of their prey (see Random Underworld Ecosystem Parts One and Two, posted below)
