It was either in the late 80's or early 90's. I believe it was a commercial for a fruit snack.
The only part I remember is a shipwrecked girl - 10 years old or so - sitting on an island in a torn and tattered dress. She puts one of the snacks in her mouth and a torrent of water splashes down on her.
I've only seen the commercial once when I was little and I've spent countless hours searching Retrojunk and Youtube looking for it, with no luck.
Does anyone remember this? Is it on the site somewhere. I searched through all the fruit snack commercials I could find, most notably Gushers, with no luck.
