The goldfish slogan 'The snack that smiles back' implies that the goldfish cracker is sentient enough to not only understand that I am smiling, but it also has the facial muscles to copy and return the facial expression to me, all the while aware of it's impending fate of being eaten. Furthermore, this slogan implies that the people who create the goldfish crackers have dominion over artificial life and the ability to create it, all the while granting the sentient cracker edibility. Does this mean the people who make goldfish crackers are hinting that they have the key to life? And good nutritious Edible Yellow Fish?
