Looks who's having a ball with his new favorite ball!
It's exam number 18 (Wow! 18 Exams!) for the San Diego Zoo's Xiao Liwu, the baby panda cutie that has us gushing with ADORBz juice.
After he was completely spent during his 16th exam, the zookeepers decided to keep Xiao Liwu active.
We need this PRESCHUZZ babe awake so we can snuggle with him!
Watch (above) as Xiao Liwu gets his latest checkup!
