A zombie apocalypse set off a thrilling dance Saturday afternoon in the downtown Chico City Plaza. More than 200 dancers performed for the fifth annual Thrill The World event. 20 different countries are involved with coordinating their own thriller dance. This year Chico's group is raising the money for a non-profit organization Arts For All, the program teaches teachers and their students inventive ways to create art. Last year Chico raised $800 for Arts For All and this year they are looking to top that amount.
