Late last year I did a head to head between Shoogy Boom and Pop Rocks, just to see if the original is actually the best. I actually prefer the Shoogy Boom brand, made by Hleks in Turkey. While Pop Rocks were displaying their new Pop Rocks Milk Chocolate Bar at the All Candy Expo, Hleks was quietly showing their chocolate popping candies as well. I don't know how long these have been on the market, the copyright on the back of the package says 2003 ... and also says that these are a product of Impact Confections (known for their Warheads line).
These little chocolate spheres are smaller than a malted milk ball but larger (or perhaps just more spherical) than a Peanut M&M. They look a little waxy, but smell pleasantly sweet. (I can figure that I beat them up pretty bad on the trip, because they were unmarred and glossy at the All Candy Expo booth.) Each sphere is milk chocolate mixed with unflavored carbonated hard candies. With the popping candy mixed with chocolate, I find initially chewing them a bit to expose the carbonated bits helps to activate them. The chocolate isn't stellar on these, but they're just the transportation medium for the popping. They flavor is a little malty, with the popping bits adding only texture and sound with a little extra sweetness.
They can get kind of noisy inside my head and I was surprised at how well I could hear the popping inside other people's heads when I passed them around last night when the neighbors came over. I don't know if I'd eat them often, but they're kind of fun. I wish the chocolate as a bit better, but these might be fun to mix with other things in a "movie mix" (but maybe you wouldn't be able to hear the movie?) like popcorn, SnoCaps and Junior Mints. I like the spherical design of them a bit better than the bar format of the Milk Chocolate Pop Rocks Bar. I shared most of them, which is the way candy should be!
