This is a "major" development!
Mountain Dew has unveiled a new permanent flavor for the first time in over a decade, with their new Major Melon drink. As you probably figured out from the name (and the picture for this story), it's a watermelon-flavored pink beverage available nationwide in bottles (20 oz. or 2-liter) and 12 oz. cans.
Major Melon is available in regular and zero-sugar.
