Two pandas in southern China abruptly transformed from calm bamboo grazers to startled fluffballs when a keeper threw bamboo shoots their way.

The funny video was filmed in the Chengdu Research Base of Giant Panda Breeding on September 2.

As the two pandas sat face-to-face peacefully munching on their bamboo meal, both of them suddenly rose to their feet, bumping heads in the process. Not stopping there, the duo swiftly turned and synchronized their movements, standing back-to-back. The amusing spectacle had the surrounding tourists in fits of laughter.

The woman who captured the hilarious video, Ms Wu, shed light on what caused the sudden panda pandemonium. She explained that the two pandas, affectionately named "Gaozi" and "Mianmian", were startled when a zookeeper threw bamboo shoots into their cage from the door. This unexpected surprise led to the comedic display caught on camera.

"Pandas are naturally skittish," she commented, adding a word of advice for future visitors. "It's best not to be too loud when touring their enclosures."

9月2日，四川成都大熊猫繁育基地内，两只面对面吃竹子的大熊猫忽然猛地同时起身，两头相撞，接下来它俩又极速转身，神同步地变成了背对背，把围观的游客都逗乐了。据视频拍摄者吴女士介绍，两只熊猫分别叫糕子和面面，当天早上是因为饲养员从门外向笼子里丢竹笋，结果把两个家伙同时吓了一跳，才发生了视频里的一幕，熊猫本身很胆小，建议大家游玩时也不要大声喧声。（视频由吴女士提供）
