First Chapter - Swap Outs
"Okay, everypony, we'll need to use our best tactics to make sure these pranks go off without a hitch," said Twilight. Tomorrow was Prank Day, and that meant everyone was going to be pranking each other. Last year, Dash had switched around all of Twilight's books, upon which she made all the water, at random times, shoot at her with high pressure. That started a prank war which started the yearly holiday Prank Day. Now Twilight and Dash, as well as Pinkie and Discord, were teaming up to prank Ponyville. "In case of an emergency, we'll need something to get us out of a situation. Dash, I'll need you to get some cardboard from the mail department. We'll enchant it so that if we are in a hairy situation, the cardboard cutouts of us will take our place."
"But Twi, couldn't we just teleport out of there?" Pinkie questioned.
"Dash couldn't, and teleports leave a magical signature. Besides, it'll frustrate them. Go!"
15 minutes later, they had the boxes. Pinkie and Dash flattened the cardboard, Twilight cut out their silhouettes and colored them, and Discord enchanted them to replace the respective ponies (and him). At the end, they had 25 cutouts of each pony.
"Let's go test out our new inventions," said Twilight, "We can do some funny things, and we'll need to make sure our Swap Outs work before tomorrow."
The four of them then went into town. Upon the way, they encountered Rarity. "Oh, Twilight, thank goodness! I need a model for my new dress and you'd look perfect in it!" Judging by her face, Rarity actually wanted to test a prank that was sure to do with the dress.
"Are you sure? Prank Day is tomorrow, and I'm not sure I want to find out if this is a real dress or just a new prank," Twilight said, "Besides, we're not real." The cutouts fell to the ground. Rarity's eye twitched.
"I guess it's a success." Twilight sighed with relief. "It was probably a dress that would restrict my movement so that I couldn't move. It would make it very hard to do any pranks with that on."
"Let's just set up the rest of the prank items before sundown, okay?" Discord was unusually serious when it came to preparing for pranks. He obviously wanted to make chaos, but he new that if you prepare things just right, you can get the most satisfaction. And he wanted tomorrow to be satisfying.
"Okay, for the next prank..."
