The Buttonwood Park Zoo hosted it's first Baby Boo at the Zoo-  a "mini" Halloween party with with educational activities, an up close and personal visit with an animal, toddler friendly snacks and a costume parade.

Judges saw more than 450 children march by their table competing for the Cutest Costume, Best Animal Costume, Best Mother/Child Combo Costume, Funniest Costume, Best Brother/Sister Costume Combo, Spookiest Costume, Most Colorful Costume, Best Superhero, and Best Princess.

Buttonwood Park Zoo's Lance Gundberg Marketing and Visuals Coordinator said the zoo did not anticipate a crowd of this size to turn out for its inaugural Baby Boo but it was incredible none the less. The original Boo at the Zoo's last night is tonight from 6:00- 9:00pm tonight.
