Space Crabs?

You know how bookstores have those shelves full of deep-discount items? I love looking at all the stuff marked-down by 99 percent--not buying any of it, just looking at it. (What? Isn't that normal?) So, I was poking around the shelves at a major book retailer when I found this:



The box on the right obviously has a crab as the centerpiece (representing, of course, cancer in the zodiac), but what's that on the left? Is it the thirteenth sign touted in the news recently? My theory is it's the flying saucer that the crab on the right arrived in.

Yes, Monsieur Space Crab, I am on to you!

So, watch out people. The space crabs are among us.
