The scene showed Rick dispatching zombies when he spots a deer hunting for food in a pile of trash.
The hardened survivor then climbs a ferris wheel to shoot the deer for food, but changes his mind when he spots a group of zombies heading his way.
It's when Rick looks down on the deer that the animal's CGI team seemed to give up with a badly lit, blocky animal that looked like he'd been Photoshopped into the shot.
One fan said it was so bad it looked like an animal from Minecraft accidentally wandered onto set.
