The Sarcophagus is a jet black metal container designed to contain the villainous and powerful Su Wu. A lock on top of the container unlocks the two doors which swing open. There is also a small padlock on the two doors of the container.
HistoryEditJinzhou Palace, Wan and Wing Wu escaped their respective prisons and sneaked into the palace where their sister was imprisoned within the sarcophagus. After sneaking past the guards and using a claw to unlock the container, Su Wu and her sisters escaped, but were later recaptured by the young warriors Thundering Rhino, Storming Ox and Croc.
In the present time, when Po, Tigress and Mantis entered the Master's Council exhibit, the sarcophagus was one of the artifacts Po marveled over. Tigress and Mantis' ignorance of the history behind the sarcophagus led Po to tell them the story of how Rhino, Ox and Croc came to be the masters of Gongmen City.
When Po finished his story, Shifu arrived and discovered his students. Excusing Tigress and Mantis, Shifu told Po to repair the hole he had made in the ceiling before the exhibit opened in twenty minutes, and left the panda to complete the task. Before Po could even begin, he tripped backwards over the cement bucket and ended up locked in the sarcophagus. After failing to get out, Po decided to take a power nap before the exhibit opened.
