Sleepy Panda Roly Poly

It was a perfectly executed forward roll - even better for the fact that this panda managed it in his sleep.

The animal, called Tai Shan, was sitting in his zoo enclosure when he began to doze off, his eyes flickering open and shut before he succumbed to sleep and slumped forward.

The sleepy panda could have fallen flat on his face. But instead he popped his head between his legs and turned head-over-heels before landing on his back.
