Zoe the Zookeeper’s Howlerween Adventure

Kids can follow the adventures of Zoe the Zookeeper as she helps wildlife officials rescue, rehabilitate and release howler monkeys back into the wild. Kids will learn what howler monkeys eat, what belongs in the Belizean jungle for a healthy habitat and more. Kids will earn a special howler monkey-themed Conservation Hero button for helping Zoe!

What is a howler monkey?

This activity includes a merchandise table with goodies for sale, such as pet rocks, animal paintings, face painting, magnets, and conservation bracelets. The table is open Saturdays and Sundays during Zoo Boo from 10 a.m. – 3 p.m.

During Zoo Boo, we are proud to offer candy made with sustainable (zero-deforestation) palm oil that doesn’t harm wildlife or their habitat. Learn more about sustainable palm oil and how you can help save animals in the wild during this Halloween season.
