Join Big Bird and Elmo as they explore the night sky with Hu Hu Zhu, a Muppet from "Zhima Jie," the Chinese co-production of Sesame Street. Together they take an imaginary trip from Sesame Street to the moon, where they discover how different it is from Earth. They also journey to Zhima Jie to learn about the similarities in our view of the sky.
