A shift stone is a mystical, red-colored stone that enables the user to assume the appearance of other creatures. Two of these stones were first seen in use by Po in the episode "Jailhouse Panda" from Kung Fu Panda: Legends of Awesomeness, who used one to infiltrate Chorh-Gom Prison and interrogate Tong Fo.
Shifu demonstrated the stone's power to Po, as the latter used it. At first, it seemed like nothing happened. But when Po looked into the Moon Pool, he saw himself as a goat, which is what he would appear to be to others. However, Shifu intended for one of the Furious Five to use the stone to infiltrate Chorh-Gom Prison to figure out where Tong Fo hid the Sacred War Hammer of Lei Lang. However, Po decided to use the stone to go in alone to prove himself to Shifu. Shifu discovered the stone's theft and used the other one to disguise himself as a crocodile.
