It’s the battle of the ventriloquists and their "Dueling Dummies" when Reggie and Archie compete to see who can throw their voices — and their insults of one another — further!

Unknown to Mr. Lodge, however, a pint-sized pilferer and his hefty henchman are crashing the party — masquerading as a man and his dummy, of course! Can Reggie and Archie stop their feud long enough to stop the tiny terror and his tiny-brained lackey from making off with the Lodge family jewels?
