The listing, Zombie arm has ended.
I understand how challenging it can be to keep and care for pet zombies. If your zombie's arm should fall off, where are you going to find a replacement at this time of day [or night, I don't know where you are]?
Look no further! Your zombie arm replacement problems are solved! Simply purchase this little arm, add water, and it will grow to a larger size and your zombie could maybe end up better than new once you've managed to install this replacement arm!
Note: This arm appears to be specifically formulated for use with brain dead zombies, but I bet it would not be too difficult to modify for use with the scarier more modern zombies that still have some brain activity.
I apologise for the quality of some of these photos. My house zombie used his potato camera to take these and I think he did a really good job, don't you?
