In exchange for a break from Panda's grueling training, Skunk journeys to The Hill of Moons deep in Dragon's territory to retrieve some of his master's favorite plums. Fox, Rabbit, and Tiger worry about Skunk, and they decide to follow him. Skunk soon finds himself fighting for his life when he's ambushed by Baboon and the Ninja Monkeys.

The kindhearted Skunk takes in a Ninja Monkey who was kicked out of Baboon's army. But Panda thinks that that monkey is a spy. Skunk figures out that the Monkey is not telling the truth and tricks him into telling Baboon that they are planning a massive attack.
