In a martini shaker or tall glass, combine the remaining blueberries, vodka, Fresh Sour, and Simple Syrup. Muddle the ingredients together, breaking up the blueberries. Add ice and shake well.
Add the lemon-lime soda and strain the cocktail over the cotton candy in the martini glasses. Serve immediately.
