retired costume that, on its own, could only be obtained via a 2011 Facebook Contest. You may think it is just a green gravestone with a couple of bones lying around it, but there is a zipper at the top of it, revealing that it is a costume. It was also given away in Nov 2005 along with the Mutant Costume. Your pet turns into a Zombie if it is neglected. All Zombie pets are green with blue eyes (old pets have red eyes) and missing or decayed body parts. They can be adopted from the Graveyard for FREE. It takes 14 days for a pet to get a place at the Graveyard and during this time, the owner of the pet who has died can save the pet from entering it for the last time.
