Rarity interrupts Applejack and Rainbow Dash in the middle of their lounging on the beach and tells them she lost one of her one-of-a-kind earrings. Applejack and Rainbow agree to help her find it, and she supplies them with some metal detectors. Rarity, Applejack, and Rainbow spend all afternoon looking for Rarity's missing earring, but all they find is a variety of other lost beach junk. Rarity apologizes for wasting her friends' day, but they've enjoyed the thrill of discovering things under the sand. When Rainbow Dash sees how distraught Rarity is over her lost earring, she uses her super speed to look through the pile of junk one more time. She finds an earring, but it's not the one Rarity lost. Rarity thanks her friends for their help and decides to do one more search with the metal detector. Just then, she discovers her earring was never missing—it had gotten tangled in her hair, much to her embarrassment.
