Tattoo ads and branded candy come together.
"Here's how Tongue Tickling Tattoos work: The tattoo is made through edible ink technology. So you wet your skin, place the tattoo on the moist area for 10 seconds, and the temporary image - Spider-Man, for example - appears on your skin. You can lick the candy until it's gone or wash it off with soap and water. And, yes, the ink will even transfer to your tongue."
To promote it's new drink, Hi-C, "Coca-Cola placed 2 million edible tattoos on a Hi-C advertisement in a double Teen People magazine issue [last] year."
