Alvin, Simon and Theodore are brothers who tour the world as famous rock stars and still manage to go to school. Completely normal… right? Did we also mention that they're chipmunks? Along with their best friends, The Chipettes, Alvin and his chipmunk brothers cause tons of trouble on and off the stage while their dad, Dave, tries to manage these three rambunctious rodents, while writing all of their hit songs. Alvin, Theodore, and Simon are so different, it's hard to believe that they came from the same litter. With little voices and BIG personalities, there will be no shortage of adventures when these chipmunks hit the stage!
