Awww that is kindov unfair to slugs.
I often save slugs, I have even denominated the wall outside my door - the wall of death, because slugs and snails will creep it during rainy weather, for then to crawl around in dumb, desperate circles, getting nowhere, slowly drying out. (the wall is alongside a step down, about 2 feet below ground level, so snails slugs, earthwords and spiders frequent here. But even earthworms are pretty swift, compared to a slug.
I like gastropods!
