Pop sensations Alvin, Simon and Theodore end up in the care of Dave Seville's twenty-something nephew Toby (Levi). The boys must put aside music superstardom to return to school, and are tasked with saving the school's music program by winning the $25,000 prize in a battle of the bands. But the Chipmunks unexpectedly meet their match in three singing chipmunks known as The Chipettes -– Brittany, Eleanor and Jeanette. Romantic and musical sparks are ignited when the Chipmunks and Chipettes square off. The filmmakers have picked the musical mix well, with songs including Katy Perry's "Hot N Cold" and the Bee Gees' "Stayin' Alive," no doubt an effort to play to the generational spread they hope will fill those theater seats. And the script includes enough clever moments to help put "The Squeakquel" in solid family entertainment territory. The Chipmunks' obsession with Animal Planets' "Meerkat Manor" proves to be one of the best running gags, particularly since the Whiskers' internecine squabbles so mirror the 'Munks high school issues. But it's the Chipettes' cover of Beyoncé's "Single Ladies," you know, "If you liked it then you shoulda put a ring on it. . . ." that is not to be missed. Seriously.
