Kellogg's: Marshmallow Magic. When you unwrap a Rice Krispies Squares Bar, you're unwrapping a one-of-a-kind ingredient that makes expected things extraordinary. The ingredient? Ooey-gooey marshmallows. To demonstrate this, we created an original music track and 3D-animated spot featuring Snap, Crackle and Pop travelling through a fantastical world, all generated by the bite of a Rice Krispies Squares Bar.
