I’m Losing My Head!

Zany Zombie becomes headless - after a horrible freak accident! Ouch! Now, Zany wants to have his head attached back to where it belongs. Right on top of his body. Zany travels back in time to prevent the accident from happening - so that he won't lose his head. But it seems he fails, and heads just keep rolling onto the floor! Zany is really hard-headed about saving his head! But he better not lose too many heads!
