Viral is an episode of the ALVINNN!!! and The Chipmunks series.
After Brittany and the girls release a video that goes viral, Alvin, Simon, and Theodore try to top it.
When The Chipmunks exit class to see a group of students causing a commotion, Theodore believes it's someone famous so Alvin tries to penetrate the crowd for an autograph only to be surprised to hear Brittany. Alvin expresses his confusion before Simon shows him The Chipettes' viral video consisting of the girls lip-syncing to the boys' songs while in a car. Upset about the video's success, Alvin proclaims he and his brothers can make a viral video too. At the Seville House, The Chipmunks review a mirror version of The Chipettes' video before publishing it. They stare at the screen waiting for the video to go viral, but after hours of doing so, they only get one view, which turns out to be Theodore who just wanted to improve Alvin's mood. Following a video comment by Theodore that causes a scuffle with Alvin, Simon decides to feed viral videos into a program he wrote in order to learn the ingredients needed for the perfect video. The next morning the boys work on a new video including cats and a "Gangnam Style" routine. They think it looks pretty bad, though given it has everything a viral video needs, Alvin convinces Simon to put it online. The video immediately becomes a hit with lawyers, and to save Mr. Piggy, Theodore throws the computer out the window. Alvin hears Dave singing and decides to film him in the bathroom; Dave learns of the video and tries to confront Alvin, who had covered himself and the kitchen floor in oil for another video, causing the two to slide around the kitchen.
