Well, I wouldn't call him a friend so much as a visitor. I found this guy the first night after my move into my boyfriend's house. Enjoy the narration. I do realize that his trail is not poop but mucus even though I reference his poop trail. The mucus is what allows slugs to climb up vertical surfaces. Pretty cool.
