JeneratorReady, you can be certain that the level 6 zombie that randomly appeared on your list is from Facebook if it is your only friend that you cannot delete. That's what irritates me about the automatic Facebook friend additions more than anything. I would highly recommend this game to several people I know but I'm friends with all of them on Facebook so if they all took my advice and gave it a try, I'd likely eventually have a whole lotta zombies I couldn't delete.
