Happy Prankday!

        Once upon a time, in the beautiful land of Equestria, there were two regal sisters who ruled together and created harmony for all the land. To do this, the eldest used her unicorn powers to raise the sun at dawn, the younger brought out the moon to begin the night. Thus, the two sisters maintained balance for their kingdom and their subjects, all the different types of ponies...

        ...but, as time went on, the younger sister had a hissy fit, because no pony was paying any attention to her. One fateful day, the younger alicorn refused to lower the moon in an attempt to commit genocide on all life the planet had to offer. The elder sister tried to reason with her, but the hate in the young ones heart was too great. So, she told her sister to "Screw off," Thus, transforming her into the stereotypical evil villain, Nightmare Moon! She vowed that she would shroud the land in eternal night, killing all that had ever ignored her.

        Without a second thought, the Elder sister harnessed the most powerful magic known to ponydom, The Elements of Harmony! Using[d] the magic of the Elements of Harmony, she defeated her sister, banishing her permanently to the moon FOREVER! Now with her younger sibling out of the way, the eldest took responsibility for both the sun and moon, making her the only princess in the land and the undisputed ruler of Equestria.

Six Months Later...

Year 1 Celestia's Reign.

(Luna's Birthday)

        "I wish Luna was here," Celestia sighed quietly, as a long line of ponies stretched far across the royal throne room in her vision. All of them, every single one, had stacks of paper held firmly in their hooves. The papers they carried were most likely new laws or requests that they wanted brought to life.

        "I really should have thought this whole 'only ruler' thing through before I banished her." Celestia let out another sigh.

        "And, that's why I believe we should build a great wall around Equestria!" The brown colt standing in front of the throne finished.

Oh ponyfeathers, I didn't catch a word of that. There, was a short lived pause in the room.

        "Yes, I agree with thee 100%. That was a brilliant speech and an even more so brilliant idea, it shall be done," Celestia spoke in a royal tone.

I hope this doesn't come back to bite me in the flank.

        "Oh, thank you, THANK YOU!" the colt exclaimed, exiting the scene.

        "Next," a royal guard called out.

I can't take this anymore, Using her magic, Celestia pulled the sun out of the sky, replacing it with the moon. "Oh my, it seems as though today has just flown by." Celestia said with a chuckle, trying to maintain her best poker face.

        "B-but, I've been waiting in line all day" The purple mare who was next in line complained.

        "I'm sorry, my little pony, but the day is done." Celestia explained, flying off of her throne, towards the exit. "Go get some rest, I shall grant more requests on the morrow."

        "Just fantastic," The mare yelled, a grump in her voice. She walking out of the room with a horrible look on her face.

Location: Celestia's Study.

Time: A Few Hours Later.

        "Now, to get down to business." Celestia whispered, looking over the blueprint entitled "Happy Prankday Luna!" which sat on the desk in front of her. On the blue print was a terrible sketch of what seemed to be a catapult loaded with pie. "Oh, this is going to be simply, AMAZING!" Celestia yelled, following it up with a very loud, evil laugh.

        "Is something the matter princess?" a guard inquired, opening the door to Celestia's office.

        The sudden intrusion caught Celestia off guard, causing her to choke on her own laugh. "No, no, everything is fine," Celestia paused, wearing a sly grin. "Everything is fine."

        "Well, uh, if you say so..." The guard went back to his station, closing the door behind him.

        "Man, that was cliché." Celestia commented, going back to her plans with an evil smile making its way across her face.

Outside Canterlot, some time later.

        "Are, you sure this is going to work your highness?" A old gray colt butler's suit asked, displaying concern in his voice.

        "Yes, Wilfred! My plan is flawless!" Celestia answered, from atop a catapult, holding a pie in her hoofs.

        "Pardon, my asking but I fail to see what part in 'Shooting yourself to the moon via catapult, just to throw a pie in your sisters face.' is flawless."

        "Absolutely everything!"

        "Excuse me?"

        "Everything, my plan is foolproof." Celestia straightened a pair of goggles on her head. "Now, if you have nothing else to add, could we please continue!"

        "As you wish," Wilfred replied, trotting over to the rope that held the catapult back, a large pair of scissors in his hoofs. He froze just before cutting the rope. "Are you absolutely-"

        "Yes!" Celestia yelled with an impatient groan.

        "Alright then,"

        And, with that Celestia was flying through the air at an incredible speed.

Just you wait, Lu- Suddenly Celestia's jaw dropped, as finally she had finally noticed had the rope that was tied to one of her hind hoofs.

        "Oh, sh-" Celestia slammed into the ground, the force of the impact shaking the earth.

        "Ugh," Celestia rolled over in pain, the pie crushed on her face. She whipped it away. "Remind me never to do-" Her eye's opened in terror as she noticed yet another pie flying directly at her. "Seriously!?" She yelled, just before getting slaked in the face with another pie, the impact spreading yummy pie goodness everywhere. Celestia moaned in pain, removing the pie that was lodged to her forehead.

        "Are you alright!?" Wilfred asked, galloping towards the mess that was Celestia.

        "Tis’ but a scratch!" Celestia called back, knocking a note loose from the pie pan with her wobbly hooves. "What's," She read the note, "Happy Prankday Tia!" Without warning, a cartoon -styled boxing glove shot out of the pie pan, hitting her square in the face for the third time that day. Celestia's head whipped to the ground, causing her eyes to roll into the back of her head. A single thought running through her mind, You win this round Luna, as she fell into unconsciousness.
