Yep, I just joined in the Killer Rabbit game. We'll be crocheting little fluffy bunnies of doom then sending them out to be killer rabbits, very similar to Sock Wars. For those of you who do not understand the Killer Rabbit theme:
That should help. You can either sign up on Ravelry (look for Killer Rabbit group) or look for the yahoo group of the same name. Currently it's crochet only, but sounds like they're trying to make a knit version too.
Killer rabbit, run away! Run away!
