As the pilgrims continue their journey, Monkey sees that a nearby village is being terrorised by swarms of locusts, and they're coming in their direction. Led by the power-hungry Demon Queen Grasshopper, the locusts follow the magic Lake Lok-Nor as it moves from one place to the next. Everywhere they go they bring death and destruction. Can the pilgrims stop them, or will the Queen turn everyone into pigs?
