Role in the Comics
After previously being manipulated by Queen Chrysalis and the Changelings into hating their friends, Rainbow Dash and Pinkie Pie find themselves in an open field surrounded by Jackalopes. Pinkie admires how "Squishy-wishy" they are, as Rainbow Dash tells them that she needs some comfort space away from them and that they need to go.
Then one of them bites Pinkie's leg and the two ponies realize that the Jackalopes are vampiric creatures. Dash grabs Pinkie (who doesn't mind being bitten) and flies off as Rarity and Applejack are floating on magical plants. They then crash into each other, get up and run from the Jackalopes, only to crash into Twilight Sparkle and Fluttershy, who was being chased by a Chupacabra.
The group is then run off a cliff and, as they hit the bottom, they look up at the Jackalopes and Chupacabra. As the creatures start fighting, Fluttershy says that they are natural enemies and that they are fighting over who has the dominance over who has the rights to eat them.
As the group looks up in shock and horror, Fluttershy smiles and says "Nature is so fascinating."
- Jackalopes are creatures from North-American folklore.
