7-Eleven teamed up with Green Day and Punk Bunny, founded in 2023 by Green Day’s Billie Joe Armstrong, Mike Dirnt, and Tré Cool, to launch an exclusive Slurpee drink flavor: Kerplunk Kandy Grape. This “sweet and slightly twisted” flavor recalls the band’s 1992 album Kerplunk! and features a flavor that mashes up the juiciness of grapes with the sweetness of cotton candy. The storytelling flavor also references the cotton candy grapes Green Day keeps on hand for backstage snacking.

The Kerplunk Kandy Grape is available for a limited time at participating 7-Eleven, Speedway and Stripes stores. What’s more, 7-Eleven and Green Day are bringing out three new and exclusive Punk Bunny coffee varieties to participating stores: Mike Dirnt’s Turn Up the Bass Medium Roast, Punk Bunny Cold Brew Caramel Latte and Chocolate Almond Specialty Latte.
