Pinkie Pie has lost Starsong's dancing shoes. She'd looked for them everywhere and still hadn't found them when Starsong arrives. She confesses she can't find the shoes so Starsong suggests dancing without them but it's not as fun. They both look some more for the shoes, they look in the closet but the shoes are under the bed and the shoes dance themselves into view. The ponies wear them and put on a dance show, asking the viewers to join them.—Kagemusha_74
