NEW YORK Salty chips, chocolates and cheese puffs are cast as "scary snacks" in a Dunkin' Donuts Smoothies print effort from Hill, Holliday, Connors, Cosmopulos in Boston. The ads roll out in magazines through the summer, positioning the drinks as alternatives to less-healthful treats, which are cleverly arranged to appear menacing. For example, the cheese snacks form a spider, while a bag of chips sports a gaping, spike-toothed maw. The headline: "Makes other snacks look scary." The colorful visuals are eye catching, and though the actual smoothies aren't shown, the ads make a case for tossing the toffees in favor of a Dunkin' fruit-flavored swirl.
