LOUISVILLE, Ky. (WDRB) -- Boxes of candy are arriving at the Louisville Zoo.

The candy will be given away during what the Zoo calls, the "World's Largest Halloween Party." It starts Saturday.

Workers are busy putting up holiday decorations around the Zoo. More than 500 UPS employees volunteered to help set up. 

"This is part of our Global Volunteer Month, where we will volunteer about 250,000 to 300,000 hours in the city of Louisville alone," said Mike Mangeot, spokesperson for UPS.

Halloween events at the Zoo run through the end of October.
