Zombies are a type of character that appears partially in Wrecked, but mainly in Extra Lives.
They eat other zombies, along with humans, too. They eat any edible object in-game, and can be eliminated by destruction of the head. In Extra Lives, when they die, they are placed in the "Deceased" category. A purple syringe or potion can heal them, and make them human, but it can also turn living characters into zombies. With the editor, you can manually make someone a zombie or turn them back into a human.
