The Tongue of Saiping is a Shen Gong Wu that is a plate with a tongue that allows the user to talk to and understand animals. This Shen Gong Wu allows the user to command the animals. Combined with the Monkey Staff it will give the user the control of an army of green monkeys, but only on the Year of the Monkey.
It was first revealed in the episode Royal Rumble, where Clay and Tubbimura had a showdown for it, which Clay lost, but the monks stole it back at the end of the episode. It was stolen by Jack in the episode Year of the Green Monkey, and was used to control an army of green monkeys. It was returned to the monks at the end of the episode Dangerous Minds, and they have had it ever since.
