Continuity mistake: After trying to entice the primitive tribe with flashy clothes and a boom box, Alvin and Simon get tied to a hut. The four ropes around their wrists are initially tied together in one knot right above their heads. But once they notice that Theodore is being pampered like a god, Alvin and Simon's wrist ropes are suddenly knotted separately instead.
Continuity mistake: In the final scene where Miss Miller is sitting next to Theodore adjusting her hair in the car's busted rear-view mirror, the shot changes to Dave opening the passenger's side door. But as he steps in, Miss Miller skids away and Theodore can now be seen sitting with the other Chipmunks and Chipettes in the back seat.
