The US has strong regulations about packaging non-food inside of food. Putting a lollipop on the end of a flashing LED[1] is fine, but crossing the border with toys embedded in chocolate will get you detained by customs and fined $2,500[2].

If fact, it wouldn't surprise me if the only thing in the wrapper is a golden coloured tracker emblazoned with the word's "you won!", and the winners task is to wait for Nestle to come to him and deliver the 10000 pounds and missing chocolate bar (tough luck if you had the munchies).
If fact, it would be quite fun evading the "Nestle police" for as long as possible, leading them on a merry chase across the UK.
