Summer Camp / Wacky WednesdaySummer Camp: The Chipmunks and Chipettes are sent to a summer camp that is actually split into two separate areas that are run by two brothers, Auggy and Austin. Auggy's half of the camp is in ruins due to Austin's repeated attacks of vandalism, so the Chipmunks and Chipettes band together to help Auggy clean up his half of the camp, while also helping him boost his confidence to stand up to his mean older brother and show him that he is just as capable of running an entire camp as well.
Wacky Wednesday: Alvin and Jeanette wake up to discover that they are each inside the other's body, and conclude that it is because of a mishap involving Simon's newest invention from the previous day: a switch ray. While Simon plays hooky so he can work on rebuilding his ray that he had taken apart, believing it to have been a failure, Alvin and Jeanette must spend the day at school pretending to be each other; this causes a rift between Jeanette and Brittany when Alvin (as Jeanette) tells Brittany that she is the one in the wrong in their latest argument, while Jeanette (as Alvin) tries to call off an impending fight between Alvin and Derek after school that day.
