Trotting a mile in another princess' horseshoes is harder than either Pipp or Zipp are prepared for. Pipp thinks queen-in-training duty sounds suuuper easy. Like, all she has to do is select the soap and the menu and the place settings and the chairs and the floral arrangements and make sure everypony in all of Zephyr Heights is happy. And Zipp is sure singing and dancing will be a breeze. Except all her Zipsqueaks are suspiciously too busy being tired and sick to cheer her on. Milkway and her sister switching superpowers has put the Pegasi in a real pickle!
