Could someone explain the lore on the second strip?

Its based on a Japanese superstition that If one sees a spider in the morning, it means good luck so he or she should not kill it. However, if one sees a spider at night, it means bad luck so he or she can kill it.

Oh, this takes me back. It's a reference to the golden skulltulas from Ocarina of Time, if I judge it right. They were only visible at night, IIRC.

Is it just me or does that spider's back end look like Spider-Man's mask?
