This fall the snack aisle is going upside down because Doritos is teaming up with “Stranger Things” for a brand-new mashup flavor in time for the show’s big finale. The limited-edition Collisions Stranger Pizza x Cool Ranch chips combine the fan-favorite ranch classic with Doritos’ most requested flavor: pizza, and are available nationwide right now in both 9-ounce and 2.625-ounce bags, wrapped in special “Stranger Things”-themed packaging. If that wasn’t cool enough, Doritos is also rolling out glow-in-the-dark Spicy Sweet Chili Minis and “Stranger Things” packaging across a bunch of its classic flavors for a full Upside Down snacking experience.
