The baby Panda's were kept in the nursery. Here is one of the babies climbing and then falling. It is hard to see, but they were behind glass.
This video is a little easier to see. The baby is walking in to the front of his cage.
This video is the thing that made me laugh the most at the baby Panda's. This on was so little he was just squeezing between the bars and going from cage to cage.
