The advert was probably Alan Randall doing his seventies copy of of George Formby. I can only remember "Rowntrees Jungilees are new and nice to eat" from the adverts on the box. They came in a card-type box and my mum only bought them once if memory serves me correctly. Kinda like jellybabies in animal shapes then?
Do You Remember Rowntrees Jungilees?
