Bats!.Applejack discovers that vampire fruit bats have infested Sweet Apple Acres, and rallies her friends to get rid of them before her orchard is destroyed. Fluttershy argues the long-term benefits posed by the bats' eating habits, but Applejack dismisses her. Fluttershy reluctantly helps her friends round up the bats, and uses her Stare to keep them in place while Twilight applies a spell that eradicates their appetite for apples. The next morning, Applejack finds that her crops are still being eaten despite Twilight's spell still being in effect. During a stakeout, she and her friends identify the culprit as Fluttershy, who has turned into a bat/pony hybrid as an unintended side-effect of the spell. Fluttershy's friends lure her to a mirror using Applejack's prized apple intended for a county fair as bait, immobilizing her with her own Stare and allowing Twilight to reverse the spell. Applejack builds a sanctuary for the bats per Fluttershy's suggestion and apologizes for ignoring her.
