A boy boards a bus and stops in front of the driver, who extends his hand. Nervously, he frantically searches his pockets: he finds no coins, only a handful of candies. He opens his fist and shows it to them. "I only have Sugus," he says sadly. The driver looks at him for a second, considers the offer, and declares: "Well, I'll pay you with Sugus!" When the boy sits down, the other passengers rush to see if they can get some too. This was the premise of one of the black and white commercials that Spanish Television broadcast in the late 1970s. Back then, Sugus were one of the most popular candies in candy stores. They weren't hard, but they weren't chewing gum either; they didn't break or crunch, but rather softened slowly; they could be chewed or licked until they dissolved. But what made them especially recognizable was their perfect cube shape and the color system that allowed you to identify their flavor without having to read anything.
