This may not be a food...but it's sure a picture of a food. This is an ad for Cracker Jack (the mixture of coated popcorn, sometimes nuts...that has nothing to do with crackers) that advertises their Sonic themed prize line-up. CrackerJack is famous for always having had some random prize item in the box, so why not Sonic? The text says "All new, All Different & All about Sonic the Hedgehog". As you can see, these were released for Sonic 3, to help promote. The actual prizes were stickers & temporary tattoos. You can see 3 of them at the top there, which curiously use Japan style Tails & Eggman (rather than Robotnick)
