By far the movie's best message is that families come in all shapes and sizes and that a parent's love is unconditional. The Chipmunks learn that just because you disappoint or disobey your parent doesn't mean they stop loving you -- but it does mean there are natural or logical consequences to your behavior. Also messages about the strength of brotherhood.
Instead of "Thug Life," a tattoo says "Munk Life." Insult language like "loser," "squirrel," "psychopath," etc. The lyrics of "Uptown Funk" are changed to say "heck yeah" instead of "hot damn" in the chorus.
Lots of Apple gear: iPhones, MacBooks, etc. Other recognizable brands and companies include Speck tech accessories, Chuck E. Cheese, Altoids, American Airlines, Speedos, Pioneer, Beats headphones, Ford Mustang, BNW, Krispy Kreme donuts, Martinelli's cider, YouTube, Twitter, and more. American Idol plays a significant role, as the Chipettes are the judges. Off camera, the Chipmunks are featured on McDonald's Happy Meals and various toys, video games, and apparel.
The Chipmunks and Miles play in a country & western bar, where adults are drinking, but the camera focuses more on people dancing. While in New Orleans, people march with beads and drinks, and the on-duty air marshal is offered two different drinks containing moonshine.
