Zombies come back with features that are uniquely theirs. The most noticeable is the blue skin and changes in facial structure, and the Zombie walk. They will not walk, run, or skip normally again.
The physical appearance are not the only changes. Zombies lose skill points and have their personality replaced. They are mean, a little outgoing, active, sloppy, and a little playful. Zombie teens can go to college and become adults after graduation.
