The Llama Brothers
A celebrated and dangerous pan flute band, the Llama Brothers appear at the South Park Mall to sell their first CD and play music for it's patrons -- all they needed was a generous grant from somebody's birthday money. When they're rounded up by the United States Government with the other pan flute bands, the Guinea Pigs are freed and the Llama Brothers are taken to Guantanamo Bay. They later escape to Peru, where the band learns they are at the center of the mythical resurgence of the guinea pigs, who are only kept at bay by pan flute music. After they are defeated, the band splits up, with the boys deciding to try out a Mariachi Band instead while Craig decides not to invest in another crazy scheme.
