Bubblicious Ink'd Bubble Gum by Cadbury Adams is now available in the US.
The bubble gum comes in rolls with seven individual pieces. The Sour Frantic Fruit flavor also boasts that yo'll be "ink'd" by coloring your tongue as you chew.
As a child I specifically stayed away from candy that colored my tongue, lest the adults know I'd been indulging.
