She reached the four-month milestone on Oct. 12, but Ueno Zoo’s giant panda cub Xiang Xiang can’t quite take a bow yet--and not for want of trying.

The cute cub, who was born at the Tokyo zoo in June, is now able to pull herself up onto her hind legs by clutching a bar, and can crawl over small obstacles. She is not yet a full-fledged toddler, however, according to a zoo official.

In the latest health checkup on Oct. 10, her 14th, Xiang Xiang weighed 7.7 kilograms and measured 69.8 centimeters.

The zoo’s little star is growing molars in addition to her two sets of canine teeth, which she is getting accustomed to by occasionally chewing on giant bamboo sticks and the bars of her pen.

She has developed a tendency to nibble things around her, and all of her baby teeth are expected to have appeared by the time she turns 1 year old.
