Alvinnn!!! And the Chipmunks - Season 3

The Animation series returns again during the third season where Dave, Simon and Theodore seem to be very concerned about Alvin's safety when he decides to enter the karate competition. On the other hand, it seems that Simon lost his mind after failing to test the school and moved to a tree to sit alone away from others. Alvin tries to turn a blind eye to his bad report card, which he received a while ago and do everything he can to intercept mail before some know what happened.
