Vampire Fruit Bats

The Vampire Fruit Bats also known as the Vampire Fruitbats are creatures that appear in the fourth season of the show My Little Pony: Friendship is Magic and appear in the seventh episode entitled "Bats!". They are relatives of fruit bats and infested Sweet Apple Acres. Unlike their more colorful counterparts, vampire fruit bats come in dark colors such as black and brown, and have red eyes and long fangs. They are considered vermin by the Apple family for their tendency to suck apples of their juice during harvest season.

Role in the Series
The rest of Applejack's friends, except Fluttershy, agree to round up the vampire fruit bats. When Fluttershy suggests letting the bats have part of the orchard, Applejack briefly snaps. Fluttershy elaborates that a sanctuary for the bats would give them their own apples to enjoy, and that the seeds they spit out would grow into more productive trees. Applejack is still very hesitant about the idea, as she recalls Granny Smith's stories of the last vampire fruit bat infestation. Thinking for a moment, Twilight comes up with an idea to stop the bats from eating apples. The friends regroup at the Golden Oak Library, and Twilight says she found a spell that will stop the bats from eating apples, but it requires the use of Fluttershy's Stare. While Fluttershy is reluctant to use it, her friends convince her once she realizes what's at stake.

Back at Sweet Apple Acres, the Mane 6 round up the vampire fruit bats onto a single apple tree, where Fluttershy stares them into submission. When Twilight uses her spell on the bats, they refuse to eat apples afterward. With their mission accomplished, Applejack thanks her friends for their help. As they go to sweep up the rotten apple cores, Fluttershy looks over at an apple.

The ponies try to talk with the transformed Fluttershy or "Flutterbat", as Rarity calls her but she only hisses at them in response. When they try to make sense of how this happened, Twilight theorizes that, when she cast her spell on the vampire fruit bats, it transferred their desire to be vampire fruit bats into Fluttershy through her Stare. When Flutterbat flies off, Twilight and her friends give chase, but she easily eludes them due to her heightened bat-like senses. Pinkie Pie makes a comment about Fluttershy's Stare, and Twilight comes up with an idea. Applejack sacrifices her giant blue ribbon apple to lure Flutterbat into a trap. When she swoops down to eat the apple, Twilight and friends surround her with mirrors, causing her to use the Stare on herself and enter a trance. Twilight casts her spell again, and Fluttershy returns to normal.
