They've been gone since 1975 I'm afraid.Maybe they've evolved into another cereal or are available only in the Far East under a different name.I doubt if anyone's holding them ransom somewhere though.
(I may be wrong on some of this, but here goes....) Yum Yum I digga digga bowl full. A new kind of break-a-fast cereal. New puffed and toasted rice. New from Kellogg's...Puffa Puffa Rice !
Puffa Puffa Rice was my favourite cereal by a country mile. I even wrote to Kelloggs and asked them if they would re-introduce it, but they wrote back and said they had no plans to. Boooooo.
