We've seen cereal on donuts, cereal on ice cream and cereal in cookies. But this summer 7-Eleven decided to take the trend a step further, by incorporating the flavor of Cap'N Crunch's Crunch Berries into a frozen slurpee that turns your tongue blue. We have no idea how this came about or why, but there has been a very mixed response on social media, with some saying the first few sips do actually taste like cereal and others who were just appalled with the whole idea. It seems quite gimmicky, but we'd try it out of pure curiosity.
