ok, there were 2 different chocolates.
One was "lite". It was actually dark chocolate, if I remember, and it was whipped, so it had these bubbles in it. When you bit into it, it was almost like biting into a nestle crunch, in that it was a little crispy, but there was nothing crunchy in there, you were feeling the bubbles "pop". That's what made it "lite".
This was covered with smooth milk chocolate. Now, I don't remember getting these as a full size candy bar, although they might have been, but I distinctly remember getting them in "fun size" at halloween.
The wrapper was the color of chocolate milk, and the writing was yellow. You unwrapped it, and it was about an inch long, and flat, like a hershey's mini (unlike a snickers). And I swear it had 2 etchings on it that looked like orange or lemon slices, facing eachother.
This memory is vivid. I've searched all kinds of nostalgia candy places and have never found it.
