Cornucopia of Slugs

I was weeding my garden the other day and noticed that the grass from the lawn was tall enough that it was leaning into my raised bed - home to cucumbers.  I started pulling away the grass and there were so many little slugs.  I do not want to kill them, I just want them to stay out of my garden.  So I gathered them up and set them free in some yummy vegetation - NOT in my garden.  There were 25 and I learned that a group of slugs is called a cornucopia.
