Pinkie Pie didn't know what to do. She didn't like killing ponies. But she didn't want to die.
"Pinkie, think of all the times your friends weren't there for you. Don't you want revenge?" Rarity said, in a soft, calming voice.
Pinkie Pie starting crying. As she cried, her hair flattened. Long straight mane. Not her poffy, happy mane, but her old mane.
She started laughing. Then said: "Let's kill some ponies."
