Description:  While Dave attempts to write a song for his High School reunion, Alvin breaks Simon's time machine. Frustrated by the noise, Dave takes the boys to the park where a merry-go-round sends The Chipmunks back to 1962. They meet a younger, insecure Dave who believes he might make for a better accountant than a musician. The boys don't wish to end up as accountants as well so they follow Dave home and convince his father to give Dave another chance. As Alvin writes a new song and Simon determines the exact time they must leave at the merry-go-round, Dave rests. At his prom, the boys further build Dave's confidence and energy before they rush back to the merry-go-round, barely making it in time. Once in the present they learn Dave wishes to use the song Alvin wrote.
