First released in 1988, Slugs is literally one of the ickiest films ever made.

The plot of this Spanish horror film is pretty simple.  In a rural community, all of the local slugs have mutated into savage, sharp-toothed carnivores.  While the slugs slowly consume the locals, health official Mike Brady (Michael Garfield) wonders if maybe — just maybe — this could all be connected to the nearby toxic waste dump.

Despite some less-than-stellar performances and a plot that makes less sense the more you think about it, Slugs works.  Some of that is because slugs themselves are just naturally creepy.  However, the majority of the credit must go to director Juan Piquer Simon who truly takes this film to its disgusting extreme.  This film is probably most famous for a scene in which one character comes to regret his earlier decision to eat one of the slugs.
