The tagline they're currently going with for Sonic Splash is "Elevate the way you hydrate."
The customizable drink platform features drinks made with a choice of sparkling or still water and a number of zero-calorie or low-calorie flavor mix-ins.
The flavors I spotted include Raspberry, Blackberry, Mango, Peach, Mint, Mango & Lime, Blackberry & Pineapple, Peach & Mint, Sunshine Berry (Strawberry, Peach, and Lemon), and Hawaiian Wave (Mango, Pineapple, and Lime).
