When Jack and Annie are sent to a village in southeast China to find the fourth thing needed to save Merlin's beloved penguin, Penny, they discover they have ended up next to a large panda preserve. Unfortunately, they also realize they have been sent back in time to the day of a major earthquake, forcing them to act fast to save the lives of the vulnerable pandas.
High in the trees in the middle of the night, all of the pandas are sleeping except for Chengdu, who tries everything and still cannot fall asleep until he finds the perfect spot--atop his brother, Yuan.
Xander Panda's plan to host a panda party falls through, since he is the only panda at the zoo, but when he extends the invitation to all of the bears, complications ensue. Includes author's note on the wonders of the animal kingdom and the international effort to save pandas from extinction.
