"The goofiest fundangled bubble gum," according to the Australian International Traders. Launched in 1991, Ka Blueys became one of the fastest-moving novelty candies. I remember them around 1994-1996, and haven't seen them in the States since.
A blue-colored, raspberry-flavored candy covering a (tiny) piece of gum, these little babies left most of your tongue covered with Blue 1. I saw them mostly in the half-gallon sized jars, but they also came in cans and bags, and if my memory serves me, they cost a dime apiece.
