Somewhere in the Andes Mountains of Peru there is an area that isn't charted on the maps. It's known as the "guinea valley" that and is a place that time forgot were everything grows huge. The south park boys along with Craig and two pilots ventured through here after realizing that they were stranded on the mountains.
Deeper in the mountains there is an old ruin filled with bizarre rooms and ancient drawings telling the prophecy of the Furry Death. The boys were about to venture into a part of the temple that was filled with waterfalls face statues however Craig decided he didn't wan't any part of this and left making the other boys follow. In Machu Picchu there is a land precious to the Incas and forbidden to the guinea. It is here that the Prophecy about the Furry Death was foretold and how Craig will save the world. The final showdown between guinea and Craig also took place here as Craig both accidentally and unintentionally defeated the guinea pirate leader.
