A Prison Zombie is a zombie variant and is exclusive to Minecraft: Story Mode. They are different from normal zombies, as they have red eyes, have part of their rib cage exposed, and have gray and black skin. They wear orange outfits similar to inmates, but much more ragged and tattered. They first appeared in "Jailhouse Block", but do not appear again after.
