Films: Squirm (1976)
Location: Civilized area
Height/Weight: That of average worms.
Summary: Okay, at this rate, we're just running out of ideas for killer animals. What's next? Killer marmosets? Sky's the limit when you've endorsed killer worms.
History: In the ridiculously southern land of human Foghorn Leghorn-soundalikes, a violent thunderstorm has unearthed a particularly nasty species. There is a surge of biting land-bound bloodworms crawling about now, and these folk haven't appeared to have ever been in a truly life-threatening situation before, so they're good as dead. Worse still, local cynic Roger has more than a few worms crawling through his body, and they've driven him stark raving mad.
Notable Kills: See Final Fate.
Final Fate: Roger is stopped in the middle of his worm-addled spree when he's shoved into a whole pit of them that sucks him down and eats what's left of him. The next day, the worms just seem to go away. Then again, who's to say that they just prefer the life nocturnal?
Powers/Abilities: Can inhabit one's body without killing them and destroy their sanity in the process.
Weakness: Anything conventional.
Scariness Factor: 3-You'd have to be pretty stupid to die at the jaws of a few of these things. But in the event that your house gets packed to the gills with them...better watch your step, then.
Trivia: -Bloodworms don't inhabit the land, only the water. Most are found in the ocean.
-After this film got mocked by the MST3K crew, director Jeff Lieberman tried to save face by claiming that the whole thing was meant to be goofy.
