In this photo provided by the San Diego Zoo, the zoo's newest giant panda cub, Yun Zi, shows Meg Sutherland-Smith, San Diego Zoo veterinary clinical operations manager, that he can get around pretty well, Thursday, Dec. 10, 2009 in San Diego. The 18-week-old, 17-pound cub demonstrated Thursday that he could walk on all four legs and make his own decisions about where he wanted to go. He was especially curious when he spotted some new toys to play with, and headed over to them without hesitation.
