COAL VALLEY, Illinois — Halloween is upon us and you know what that means…Boo at the Zoo!

Hundreds of event-goers flooded the Niabi Zoo on Saturday and Sunday for a chance to trick-or-treat among some of their favorite animals.

From Dorothy from the Wizard of Oz to several Game of Thrones-inspired selections, this year’s costumes did not disappoint.
