Special Effects Failure: In the otherwise heartwarming Tear Jerker song, "My Mother", it becomes especially apparent that only one actor is voicing all three Chippettes, as they pass the melody between each other without any tonal change.
What an Idiot: Did Alvin and Brittany really believe Klaus and Claudia intended to keep their promise of $100,000 to the winning team? Or that they would still get it after learning of their actual scheme and confronting them on it? Especially egregious as the two of them demand the prize money even after the two siblings had just tried to kidnap them and had already been arrested. It takes Dave to remind them that they're not getting a cent for their troubles.
