-- Gu Gu is not your typical soft and cuddly giant panda.
For the third time, he's tasted the flesh of an unwitting intruder in his pen at the Beijing Zoo.
His most recent victim was 28-year-old Zhang Jiao, who told CNN he fell into the panda pen Wednesday while trying to catch a small toy thrown by his young son.
"My son and I were playing with a panda doll, throwing it to each other, when I dropped with the toy" into the pen, Zhang said.
The barrier around the pen is about 5 feet tall, but on the other side is a drop of 9 to 10 feet, and Zhang says he could not climb out.
That's when Gu Gu went on the attack.
