I'm not bothered by anything little, slimy or crunchy, lol, but my poor gandfather stepped, (barefoot) on a HUGE leopard slug..

It says they only grow to four inches, but i see a lot that are at least six, six and half.. What makes this story amazingly rich, is that my grampa couldn't look at earthworms and not shudder... It was so funny.

The leopard slug mating ritual is also pretty cool.. Slug acrobatics.
