Pottering around with my seedlings, I barely noticed that someone had taken up residence in one of the community pots:
When I moved the pot, he sat up a bit and took notice:
I've actually found this guy in this pot several times and evicted him each time. He keeps coming back though, and I think maybe I'll just let him stay there. I've seen some evidence of somebody or something digging around in some of my other pots, and I'd much rather have him in here, since it's a cross I don't care so much about, and the seedlings are big enough to apparently not be harmed by his (or her?) presence.
