Battle of The Bands (South Park: Bigger, Longer and Uncut 2)

Everything is back to normal in South Park (well, sort of). South Park Elementary is setting up a musical showcase and Stan, Kyle, Cartman, Butters, Kenny and Wendy are now 4th graders. They are getting Fingerbang back together for the musical showcase event! Meanwhile, 4 new girls called "The Sirens" who resemble Stan, Kyle, Cartman, and Kenny, are out to seek evil. They use their magical pendants to turn the musical showcase into a violent, and all out bloody battle of the bands. It is up to Stan, Kyle, Cartman, Kenny, Butters and Wendy to save the world from The Sirens.
