This is Nan the Banana Slug! My roomies and I are pretty sure she lives under the boards of our front step, as seen in the video. Sometimes she will crawl up between the boards to say hi, do a dookie on our welcome mat, or just hang out and receive a treat. We love to feed her our leftover fruit and veggies. Here she is munching away at a slightly-past-its-prime strawberry. We consider her our little slimy friend, and our outdoor pet. One time, she actually made it inside our house when the landlord needed to run a hose out our front door, leaving it ajar. Thankfully, my roommate noticed Nan before our landlord did, and she quickly snapped a pic and moved her back to the front step. We love Nan!
