Strangest thing seen while camping.

A couple years back we were camping in Oregon. It had been raining seemed like every day. Finally we had a nice day and we decided to walk the dog. As we were walking through the grass in our camping spot my wife got all upset and told me, some people are so dirty and never pick up after there dogs. So she pulled out the plastic dog bag and reached out to pick up somebody else mess. When she picked it up she starts screaming. I asked what is the problem? She said that thing is alive. Turned out, it was about a three inch slug. Never knew they got that big, and it did look like dog poop. Lol
