To quote from that page as it appears now:
"09:35, 29 August 2011 Kizzycocoa (Talk | contribs) deleted "Blue Spider"
(all we have is 2 tweets from a non-mojang person about a spider that is tinted blue. for all we know, this could be a bug, the result of gamma sliding, or a myriad of other things. no speculation.)"
So I wouldn't worry quite yet.
