What I also found interesting is that I wanted my slugs to have 2 vicious protruding teeth and discovered slugs actually do have thousands of teeth which I didnt realise, I knew they ate plants and leave marks where they've been munching but never really pictured them having teeth. I thought it would be could to change it from having teeth used for eating plants and to give them teeth which are capable of eating into human flesh.
They also have green blood which gave me the idea for them to emerge from a sickly-green pus as yellow-green makes people think of things that are not very pleasant like sometimes sick, snot and slime in films is nearly always shown as being green. Green or an off yellowy-green is a colour that people associate with something not being quite right or not functioning properly which again links to the uncanny because people are repulsed and scared of things that aren't quite right or aren't behaving/functioning in the usual manner.
This is an extract taken from an article I read a while ago it's about a white slug that's been discovered in Wales and is carnivorous which is actually unusual for slugs, I like the description they use for its teeth about being blade-like and sucking in like spaghetti. I think it sounds like something from a horror film yet they actually exist and are living in Wales and probably many other places.
'Carnivorous slugsUnlike most slugs, the Ghost Slug is carnivorous and kills earthworms at night with powerful, blade-like teeth, sucking them in like spaghetti. It has no eyes, is completely white, and lives underground, squeezing its flexible body into cracks to get at the worms.'
