 Two giant pandas now in their new home, the first to arrive in the U.S. from China in 21 years. Four-year-old Yun Chuan, traveling with him, Jin Bao, three years old. Caretakers say Jin Bao is naturally playful, very active, alert, witty, and an excellent climber. And Yun Chuan, he likes sleeping in. And while he's, quote, serious about his bamboo, he is mild-mannered toward others. We won't get to visit them just yet, the zoo's saying they need time to get used to their new habitat.
