One World, One Sky: Big Bird's Adventure, a 20-minute planetarium show, follows Sesame Street's 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. Children attending the show can interact as they watch, drawing constellations and counting the time it takes the sun to set.
