A panda cub and a green ball is a ridiculously cute combination.
The panda cub, Xiao Liwu, is seen here at the San Diego Zoo during his 18th checkup. He was given a ball to play with to test his coordination and encourage him to play with new things.
Xiao Liwu was born at the San Diego Zoo on July 29, 2012, and has one half-sister, two full brothers, and two full sisters.
The San Diego Zoo also has a pretty awesome Panda Cam you can check out.
