Pinkie left Twilight's castle a few hours after she had broke the vile. She walked back, not feeling so well. She was wobbling around and struggling to walk in a straight line. She bumped into some fellow ponies, and looked at them with saliva coming out of her mouth.

"You look................tasty." she says with a creepy giggle and lunges at them

Twilight's castle:

"GAH!! Making one of those potions was hard enough with magic, but now I have to do it without magic." Twilight says frustrated

She drops her head onto her worktable.

"Spike!!" she shouts, "Oh wait, he's with Rarity collecting gems. Damn it, I could us his help"

She gets  back to work, trying not to mess anything up, as she had to use her mouth and hooves to do all this.

Somewhere in Ponyville:

Pinkie looks up from her meal she had just finished and wipes away the blood. She walks away, leaving a pile of blood and guts behind her. She giggled the entire way, looking for somepony else to snack.

"I'm so.....hungry." she says with a hushed voice, "I guess I should find more prey."

She wandered all the way to Applejack's farm in search of her.

"Tiiiime....tooooo............. feeeeeeeast." Pinkie says in a raspy voice spotting Applejack and Applebllom doing some chores  around the farm.

She saunters closer and closer
