Hu Hu Zhu (呼呼猪) is a furry blue pig from Zhima Jie, the Chinese co-production of Sesame Street. His name means "Whirring Pig". Hu Hu Zhu meets his Sesame friends Elmo and Big Bird in the 2008 planetarium show One World, One Sky: Big Bird's Adventure; his first appearance since the cancellation of the original production of Zhima Jie. In the U.S. version of the show, Hu Hu Zhu (as performed by Tyler Bunch) visits America; in the Chinese version, Elmo and Big Bird visit Hu Hu Zhu in China. They learn about space together, traveling on an imaginary trip to the Moon.
