More than two-dozen trick or treat stations and creepy, crawly fun await a family fun event.
The Denver Zoo hosting Boo at the Zoo this weekend.
Children can dress up in their costumes, parade around stations, engage in animal demonstrations and meet "Thing." He's the newest character in the children's book "Yesterday's Zoo."
The fictional book is home to all extinct animals and aims to inspire kids to learn more about all living things.
Boo at the Zoo is free with admission. It runs from 9 a.m. to 5 p.m. October 27 & 28.
