Mr. Octopus gave me some venom last week when I was playing with him. If he's out playing when I open the lid he'll usually come to the top and start grabbing me. I enjoy playing tug of war, but he'd never given me more than a nibble. It felt like a very bad beesting. These photos are of my finger within about a half hour. I took some ibuprofen and slept on it, the next day my finger was still noticeable but not quite as bad as the night before.
