Watch | Zombies take to the streets in Mexico City

Thousands of Zombies roamed the streets of Mexico City last Saturday and for a good cause. The city held it's ninth annual Zombie Walk to collect canned and non-perishable goods for food banks and homes in need. The Zombie Walk phenomenon began in Sacramento, California in 2001. Since then, the event has spread to major cities around the world including New York, Buenos Aires, Bogota, Singapore, Sao Paolo and Frankfurt.
