Twilight serves Rutherford a banquet of traditional yak foods, but Rutherford destroys the banquet table because he doesn't like how the food tastes. Applejack makes him and his fellow yaks Yakyakistan-style hay beds, but Rutherford destroys them because they aren't made from Yakyakistan hay. The yak prince reacts similarly to Fluttershy's animal friends, Rarity's fabrics at Carousel Boutique, Rainbow Dash's snow, Mrs. Cake's baking, and Spike's piano playing. Eventually, Prince Rutherford becomes so frustrated that he decides to leave Ponyville and declare war on Equestria.
