Nightmare Fuel / Humans-B-Gone!

• Macrovolute territory from the human perspective is definitely no jokes, as not only is there a chance of getting captured or killed by a giant arthropod that perceives you as a mere pest, there's a host of hostile demivolutes that like the taste of human flesh, and an environment directly hostile to human life.
• Demivolute cows.
  • They're not only horrifying to look at, being essentially flesh stretched out on a skeleton and twisted into an almost insectoid shape, but they also actively hunt and ambush humans, using their horns to mash their prey into bits small enough to fit inside their mouths. One Hiver barely manages to escape this fate.
  • Simply the concept of even a perfectly normal herbivorous cow having a chance of giving birth to a mutated, woman-eating predator is pretty horrifying.
