Gu Gu is a male giant panda at the Beijing Zoo in China. He was born at the Wolong National Nature Reserve in 1999. His father's name is Pan Pan and his mother is number 21. Gu Gu was selected to come the capital zoo as a breeding candidate in October, 2004. Weighing 242 pounds (110 kilograms), Gu Gu first came to international fame not because he had the whitest fur, but because a September 2006 incident in which the panda bit the legs of an intoxicated Chinese man who jumped into his enclosure and tried to hug him. A second incident occurred a year later when a 15 year old boy jumped the barrier and climbed into the panda exercise area where Gu Gu and another panda were being fed. The startled Gu Gu reacted by viciously biting the boy on both legs. The boy had climbed into the panda enclosure out of curiosity. Since then, two subsequent biting incidents took place in 2009 and 2012.
