When I was really, really little my dad had the original Star Wars films on video he got from a "friend" who lived on a boat (I think it was pirated as my dad and uncle fell about laughing at this point)and I was absolutely terrified of Jabba the Hutt. My dad, being a caring soul, told me that slugs were all Jabba's children and if I stepped on them anymore, Jabba would come and eat me. Strangely, I never remember slugs before this point ( must have been about 4), but I never stepped on any.
Dad had to explain he was only joking about Jabba about two years later when I freaked out because my cousin's dog was eating slugs.
