Answer: They're peanut butter (brand names).
Like I said, this seemed to be fairly easy or you guys are figuring out how this works. Six people got it Monday for 3 points: EricBess, Melkor, Ransac, rokapoke, train, turgy22
Four people got it Tuesday for 2 points: Mooseman, Oversoul, sageridder, TomB
And two people got it yesterday for 1 point: DarthFerret, mythosx
Unfortunately, these brands don't show up in Limited's country so he had no idea what these were.
