Day two of Boo at the Zoo was on Sunday, October 27, 2013. Families came to Trick-or-Treat and see the animals at Niabi Zoo in Coal Valley.
Among the candy and bounce houses was the LaBooratory which offered kids an educational experience. In the LaBooratory reptiles and invertebrates were available for a close-up look, a fur-identification test, and experiments with dry ice. 2013 was the second year the LaBooratory was offered.
