The returning drink is only available through the Sonic App as part of the fast-food chain's Flavorista Favorites, which they call "an exclusive selection of curated, premium drinks that can only be found at Sonic."
The Strawberry Shortcake Snowball Slush Float features strawberries mixed into a shortcake-flavored Slush, topped with a "snowball" of vanilla soft serve and crunchy sugar crystals.
