Slugs (1988)

They ooze. They slime. They kill.

Small town health inspector Mike Brady discovers long-buried toxic waste is having an interesting, albeit unfortunate, effect on common garden slugs -- the squirmy little slimies have developed a craving for human flesh. And they've invaded the water supply! Soon, hapless townsfolk begin to fall prey to the carnivorous creepy-crawlies. Will Mike stop the rampage before the entire community becomes a section on the dinner menu?
