TAIPEI -- A long line formed in front of the giant panda pavilion of the Taipei Zoo on Friday morning, with visitors eagerly waiting to offer their 20th birthday wishes to the "celebrity" panda.

After a 20-minute wait, Yuan Yuan, the female panda, made a punctual appearance, greeted by a chorus of cheers and camera clicks.

"She's out!" said some excited visitors. "So cute!" others commented.

The panda showed no signs of shyness, confidently strolling out to face the audience before sitting down to carefully examine her "birthday cake."
