Viral / Brothers of Dagarack.Viral: The Chipettes upload a video of themselves singing a medley of the Chipmunks' songs, and end up going viral in the process - much to the annoyance of the Chipmunks, who feel their status is unwarranted for stealing their songs. Desperate to achieve viral status themselves, the Chipmunks look to the Internet to see what the popular trends are to inspire new videos of their own, only to end up getting into trouble for copyright infringement.
Brothers of Dagarack: The Chipmunks are eager to attend the premiere of the newest Dagarack movie, but Simon ends up getting sick, making him unable to go see the movie, and he does not want Alvin or Theodore to go without him. Alvin, however, does not want to miss it, and makes several attempts for he and Theodore to sneak out of the house to go see it, only to be foiled by Simon accidentally thwarting their plans as his illness makes him delusional and causes him to wander around the house aimlessly. Eventually, Dave calls him out for it, but Alvin (and later Theodore) gets sick, although Simon, in an act of understanding and forgiveness, refuses to see the movie in favor of being loyal to his brother.
