While at the South Park Mall, the boys take notice of all the Peruvian pan flute bands playing in the courtyard. Eric Cartman decides to start his own pan flute band by recruiting Craig Tucker, because he recently received $100 for his birthday. They use the use the money to buy costumes and instruments, but find the competition with other bands in the area too great to overcome.
The music played by the Peruvian flute bands is used to keep the Guinea Creatures from attacking the cities around the world. The music is a soothing melodic tone mixed with a steady beat on a hand drum. All of the songs are performed instrumentally.
