Every holiday season, Pinkie Pie bakes a dessert for Rarity and Rarity makes a holiday outfit for Pinkie Pie. This season, Pinkie Pie has baked a soufflé, but when Pinkie Pie and Sunset Shimmer step outside to deliver the fragile pie, they are immediately confronted with a raging snowball fight between Applejack and her allies and Rainbow Dash and her comrades. Pinkie Pie only has seven minutes to deliver the soufflé before it deflates. In an act of bravery, Sunset Shimmer sacrifices herself so that Pinkie Pie can run across the yard, but Pinkie Pie doesn't make it all the way. Pinkie Pie fears that the pie will fall and, thus, her holiday tradition will end. She's ready to make one last effort to save the tradition and pie when she is surprised by a special someone who has the power to shield her from the snowballs and ensure the tradition is preserved.
