The Hip Munks are robotic doppelgangers of Alvin and the Chipmunks who were created by a duo of executives who sought to replace the real singing trio in order to gain more money and fame. They are destroyed when The Chipettes teamed up with the boys, causing the robots to overload and explode during the Battle of the Bands performance of "Strong Forever."
The Hip Munks appear to have nearly the exact same looks as The Chipmunks, only with some differences: Calvin's hoodie has the letter 'C' and his cap is backwards, Simon's doppelganger has darker, stylized glasses, and Theodore's doppelganger has his hood over his head.
The Hip Munks have an unfriendly attitude towards The Chipmunks, referring to them as "lame" and "losers."
- The names of Simon and Theodore's doppelgangers are never mentioned.
