Pinkie Pie Licks The Fourth Wall
Maka-baka
"I'm gonna do it," Pinkie Pie told herself one day, after a long afternoon in Sugar Cube Corner, surprisingly arguing with her foster parents, Mr. and Mrs. Cake. Her magenta mane was sprawled out into several different strands, her bubblegum pink pelt dripping with sweat. "I'm going to lick that wall."
The Cakes had doubted her. They said she couldn't do it. Not that they were trying to put her down, but they were trying to prove that it was physically impossible. Even their foals, Pound and Pumpkin Cake, didn't seem to believe their babysitter.
"Nothing's impossible," Pinkie had told them, sticking out her tongue. "And besides, it's just like any other wall. Why can't I lick it? I've licked brick walls, wood walls, fenced walls, poison ivy-covered walls... What's the difference?"
The blue, plump mare only shook her head. It was no point arguing with her peppy employee. She simply took her children on her back, walked out of the room, and gestured that Pinkie's shift was over with a flick to her swirly, pink tail. Her husband followed suit.
So now here Pinkie was, sitting on the moist ground from yesterday's rainfall. Her eyes focused on nothing, so it seemed, her snout twiddling in anticipation. Beads of sweat rushed from her temple, surging down her hoof and plopping on the ground. Her puffy tail twitched with every passing moment.
"I'm gonna do it," she repeated absentmindedly.
The mare took a gulp and then licked her dry lips.
"Right now."
A tree swayed in response to a gentle breeze of wind.
"Any moment..."
Worms squiggled their way through a lump of wet dirt, eating it and pooping it out as they went by.
"Yep. I'll prove them wrong."
"Well what's stopping you?"
Pinkie shot her head back, checking behind her. Nopony was there, but she was sure she heard a voice... a mocking voice. Not being the type of pony to ignore something like that, she asked, "who said that?"
"Who else?"
"That's not very helpful." Pinkie frowned, furrowing her brow. She stood up, shaking her backside a bit to remove some of the soggy dirt and grass that had collected there. "Mind telling me your name, stranger?" Her voice was peppy again.
"One of your closest 'friends...'" continued the voice, in an edgy, taunting tone. "One you like to talk to... and look at a lot."
"I've never met a friend I couldn't see," she protested, blue eyes rolling around and around. "Besides the Breezies-" She snorted and burst out into adorable laughs. "-they were tiny!"
"Well, it seems you can see me. Other ponies can't, but you can. I wonder why you cannot see me now."
"Are you hiding? Are we playing hide-and-go-seek?"
If the voice was visible, it would have rolled its eyes. It breathed a sigh of frustration, the torment edge gone and an exasperated one replacing it.
Pinkie Pie received a nudge to her side. She jumped high in the air before returning back to the ground.
"Did you feel that?" the anonymous force asked.
"I did!" the cake mare replied excitedly, giggling again. "Was that you? Did you poke me, Mr. Stranger, sir?"
"I did."
"Hm..." Pinkie scrunched her face again in concentration. "What were you trying to do?"
"Proving to you that I exist. Now, I know you can't see see me. But look out into the open. I'll be standing there. And I'll put a little mark to prove it."
"Okey dokey lokey!" she chirped in response, waiting for his signal. She faced the front, eyes locking in on nothing. It seemed nopony was out today, probably due to the sluggish weather. The barren tents from Ponyville Market shook in the wind, the only thing keeping them down being the metal stakes planted into the ground.
The force seemed to get hopeful again. After a few minutes, it moved itself to where Pinkie's gaze would be, spreading itself out.
The earth pony couldn't see the movement he had made. But she did see something he displayed in the air - a marking, like he had said. It was just a simple, black and white box with the foreign characters "T" "V" together and then a "Y" under it. She swore she had seen that before.
"I see it! I see it!" She stomped her hooves on the ground in applaud. "The... 'Tee Vee Why' symbol." She had trouble pronouncing the characters she did not know.
"Good," the voice agreed.
"But what does that have to do with you, sir?"
Another exasperated sigh.
"Think about it, Pinkie Pie. What is usually associated with said symbol?"
"You know my name!" Pinkie Pie sprung herself in the air again, not regarding the rest of his sentence.
"Okay, you're going to need some help... Um... Uh..." He racked his mind trying to think of a way to explain. "So... You know your audience right?"
"My audience?"
"That's right: the people who watch you, that is... Well-"
"My life is just a big television show?!"
"Oh... boy... This is awkward."
Pinkie stood shocked for a second before she laughed hysterically. "That's so cool! If I would have known that, I would have done a lot sillier things!" She rotated herself around, perking her plot out to the open space. Quickly, she wiggled it back and forth, her poofed tail waving alongside her.
"You're not on air right now... Listen, I'll explain this later, okay? Let's just get back to the topic already." He spoke swiftly so that the mare couldn't interrupt him again. "So that label is associated with your audience level. Or it was... er, we'll get back to that on a later day... I'm sure we'll be talking a lot more. Anywho, that symbols your audience's perspective: what they see. When you look straight into the open like this, it means you're breaking the fourth wall... And that's me: I'm the fourth wall."
The party pony gasped, her curls springing out of and then back into place. "Y-You're the fourth wall?!"
"Yes-"
"Perfect! Stand still for a second..."
"Huh? What are you doing Pinkie?"
"Keep talking. I'll be there in a second."
"What do you mean?"
The horse rushed towards him, practically leaving a trail of different hues of pink behind her. He braced himself for her impact, seeing as there was no time to dodge. She slammed against the fourth wall - quite literally - and bounced back a few steps.
"Careful, Pinkie Pie. You don't want to crack the screen," he cautioned. "The viewers will be disappointed."
"Sorry," Pinkie spouted out quickly, shaking her head from the minor infliction's pain. She stood up onto her hinds, wobbling, and steadied herself out. Carefully, she leaned against him, pressing her hooves into where his mouth would have been, if he were a living creature.
"What are you doing?" he repeated, still waiting for an answer.
"I have to do something to prove something to somepony."
"What? Huh?"
Pinkie angled her face closer, opening her mouth wide. Flinging her tongue out, she planted it on the camouflaged wall, leaving a trail of saliva as she brought it up slowly.
"Gah! Pinkie!" Fourth Wall pushed her off, but she rushed back immediately.
"Just. Let. Me," she said between slurps up his "face." He kept forcing her off, but she returned after.
"Why are you licking me?!" Fourth Wall demanded, wiping the already dripping drops of spittle off himself. He switched his position, but the mare followed his voice, doing the same thing.
"Just one more," Pinkie urged, taking a longer lick from his face. Her taste buds analyzed his static taste. It was like water; hardly a taste but the hint of something there. "There we are! All done."
Fourth Wall glared at her with non-existent eyes. "What was the point in all that?"
"I've now licked every wall in existence," Pinkie Pie announced proudly. "I'll see you tomorrow!"
And with that, the mare hopped away cheerfully.
