"Twilight, did Pinkie follow you here?" Vinyl asked, knowing how sneaky Pinkie could be.
"No, Pinkie's back at Sugar Cube Corner," Twilight said with relief.
"Welcome to our house. Can I get you a bud light?"
"It's 2:00 P.M."
"I'm just joking. Could I get you some tea?" Vinyl asked, imitating Octavia.
"Vinyl, quiet down. I'm practi--" Octavia noticed Twilight and asked Vinyl with the usual Canterlot arrogance, "Oh, is this one of your friends?"
"Oh, don't mine her," Vinyl said to Twilight. "She's just stressed because she has a recital."
"I'm Twilight Sparkle," Twilight said to Octavia, "a friend of her friend's, if you must know."
"Wait, the Twilight Sparkle?" Octavia asked guiltily. "We went to Celestia's School for Gifted Unicorns together."
"Don't worry about it," Twilight said, smiling. "After all, you were the only earth pony who got accepted."
"Hey, Twilight, before I forget, here's two tickets. One for you, and one for my epic friend Pinkie," Vinyl said, hoping Twilight would accept them.
Twilight knew Octavia wanted her to go. "Yeah, I'll go. I could use the time to catch up with Octavia."

Twilight teleported to Sweet Apple Acres to make up for lost time. It was getting dark, the party was the next day, and they had so much to do.
"Howdy, Sugar Cube," Applejack said. "You look tired. Why don't you take a break?"
"A break?" Dash asked, lifting the wood to build the bar. "She hasn't done anything. We should be the ones taking a break."
"Rainbow Dash, apologize to Twilight," Applejack ordered, unable to believe Dash's rudeness.
"Sorry, Twilight," Dash said. "I just want her to have an awesome birthday."
"It's fine, Rainbow," Twilight said. "I understand. If you want, why don't you take the rest of the day off? I can help."
"Actually, Sugar Cube, I wanted to talk to you for a few minutes," Applejack cut in.
"Sure, so how are the preparations coming along?"
"We're almost done," Applejack said, stressed. "I was wondering if you could help me with the food. It'll take most of the night, and we have to wait for the shipping of the beer, wine, and other alcohol."
"Um, sure. I don't know how to cook, but I'm sure I can learn."
"You can go home," Applejack said to Dash. "Twilight and I will cook the food."
She and Twilight went the kitchen to see a whole bunch of food. Twilight was surprised there wasn't anything apple based, but there were all types of food, even food one doesn't see at a gala.
"How does Pinkie do it?" Applejack asked, tired. "She makes it look so easy."
"You're not too bad," Twilight said, blushing.
Applejack raised her eyebrow.
"At cooking," Twilight added, still red as a rose. The oven's beeping broke the silence.
"Hey, can you get the tomatos to make the pizza? I hear it's Pinkie's favorite food," Applejack said, chuckling.
"And you would know this?" Twilight asked skeptically.
"Rainbow told me."
"I thought it was cupcakes."
"Unsweetened food," Applejack amended. The doorbell rang.
"Are you expecting somepony?"
"Oh, could you get that? It's the alcohol."
There were crates of all types of drinks. Luckily, Vinyl was there. "You don't need to worry," she said. "I've been in the club scene before. I know how to set up a bar."
***
By midnight, the bar was set up.
"Goodnight, Miss Applejack, Miss Sparkle," Vinyl said, full of energy.
Applejack yawned. "Goodnight. I better put all the food in the fridge."
Twilight and Vinyl returned to their homes.

Pinkie Pie opened her eyes at 7:00 A.M. and saw none other than Derpy.
"Hello, Pinkie Pie," Derpy said with her cute smile. "How are you today?"
"Oh, it's just a normal day, but since you're here, it's going to be a good day." Pinkie walked downstairs. "Morning, Mr. And Mrs. Cake. How are you?"
"Oh, hey, Pinkie," Mr. Cake said. "We're going to close shop for today. Take a vacation."
"You sure?" Pinkie asked, just wanting to work. "I can stay here if you want."
"And leave your friend Derpy alone?"
"I need your help," Derpy said to Pinkie. "I lost some very important letters for ponies. Can you help me find them?"
"Sure," Pinkie said, being polite, though it wasn't her top priority. "How many?"
"Um..." Derpy trailed off.
"Come on, Derpy, you can tell me," Pinkie said, giving her the puppy-dog eyes that worked so well on Fluttershy. "I won't be mad."
"Ten," Derpy said, looking down. "I lost them on my route."
Pinkie and her went out to find the letters. "Derpy, lets check the mail station. Maybe they can tell you where your mail is."
"I don't want them to be mad at me," Derpy said, trying to get her to play along, looked up at a tree, and saw a letter. After they got it, they noticed it was to Cheerilee.
"Hey, Pinkie, did you know my daughter, Dinky Doo?" Derpy asked as they headed to Cheerilee's house.
"Why isn't she Dinky Hooves?" Pinkie asked, giggling to herself.
"My husband Doctor Hooves and I agreed it would be a better name for her."
"Of course I know Dinky, silly. Who do you think I am, somepony who isn't Pinkie Pie? I don't get why you and your hubby think 'Doo' is a better name than 'Hooves,' though."
Pinkie and Derpy got to Cheerilee's house. A note was on the door, saying, "I'm away. Please leave all mail on my front door."
"Oh well," Derpy said. "Let's go. We still have nine letters to find."
"I spy with my Pinkie eye," Pinkie said. "I see another letter in that bush over there." They saw that this letter was an order for some party dresses from Rarity. "Oh, a party! I love parties. Did you know I throw..." Pinkie trailed off, seeing Derpy looking sad. "Sorry, Derpy."
Derpy smiled again.

About six hours later, they'd delivered six letters, and a built Pegasus who looked like her boss told her she could take the day off.
"Hey, Pinkie, let's go get lunch, on me," Derpy said, excited, for this was completely random and had nothing to do with the party.
"Normally, I would say no, but I'm flat broke, so I'll pay you back as soon as possible," Pinkie said, winking.
Derpy giggled and said excitedly, "Rarity told me about this spa. She and her friend Fluttershy go there every week. Rarity told me it's very relaxing."
She and Pinkie were exhausted by the time they reached the spa. Derpy gave Aloe a note.
Aloe and Lotus were in on Pinkie's surprise party, so they gave them a free spa treatment that would normally be a hundred bits.
Pinkie and Derpy heard a relaxing voice that made Fluttershy's seem like nails on a chalk board, "Just close your eyes. We will take care of the rest."
Pinkie later awoke feeling like herself in the purest way possible.
***
Pinkie wouldn't be expected at the party for a few more hours, and Twilight, Vinyl, Dash, and Applejack still had so much to do.
"Hey, Vinyl, could you check the beer and make sure it's at the right temperature?" Dash asked.
"Sure thing," Vinyl replied. The guests were about to arrive, so she went to get Pinkie from the spa.
***
"Hey, Pinkie, are you ready to party?" Vinyl asked.
"Oh my gosh, it's really you!" Pinkie said. "Now I know how Dashie feels!"
"Yeah, hey, can you follow me?" Vinyl asked, feeling uncomfortable. "I have a surprise for you."
***
Vinyl lead Pinkie to Applejack's barn, covering Pinkie's eyes.
When Pinkie opener her eyes, she was in heaven.
"Hey, Pinkie, isn't this totally awesome?" Dash asked with a huge grin.
"I love parties!" Pinkie said. "Wait, who's party, and why?"
"Why, it's yours, Sugar Cube," Applejack said with a slight chuckle.
"Can I get any of you fine ladies a drink?" McIntosh asked.
Everypony looked to him in shock. Everypony besides Vinyl, that is. "Sure, we'll have two shots of vodka. Leave the bottle. Is that all right with you, Dash?"
***
Vinyl and Dash drank the bottle dry.
"Hey, Applejack, why does your barn smell Like sexy?" Dash asked out of the blue, starting a fight with Vinyl in which they were both too drunk to cause harm.
"Oh, no, I made Dashie hurt!" Pinkie said. "I'm so sorry, Applejack."
"It's not your fault, Sugar Cube," Applejack said, looking disappointedly at Dash and Vinyl.
"The party is just getting started," Octavia said, having been talking to Twilight. "Yeah, sorry there's no music, though,"
"Hello, Pinkie," Fluttershy said. "Want to dance, I mean, if you want to?"
"Um, sure," Pinkie said. "It's a party. Lets have fun."
"Like what?" Fluttershy asked.
Pinkie kissed her and said, "That was awesome!"
"Good for you, Pinkie, good for you," Dash said, just waking up.
Pinkie suddenly felt awful. She knew she had to do something. "Hey, Applejack, you keep the party going. I got to do something."
"You need help, Sugar Cube?" Applejack asked.
"I think I can do this on my own," Pinkie said, grabbing a muffin.
***
Derpy looked beautiful under the moonlight.
Pinkie called out to her in a pained voice, "I'm so sorry I didn't invite you to my party."
Derpy was silent.
"I really let you down after all the kindness you've shown me."
Derpy remained silent.
"I understand," Pinkie said, almost crying. "I'm no better than the ponies that laugh at you."
Derpy sobbed in pained silence.
Pinkie never wanted to make anypony feel like that. Putting the muffin down and walking away, she said, "I got you a muffin."
Derpy grabbed Pinkie's tail and said in a perfect voice, "I love it."
"Its just a muffin. It doesn't make up for--"
"No, you spend time with me. That's what I love," Derpy said and kissed Pinkie.
"I love you, too, Derpy. Doctor Hooves is a lucky stallion."
"Yes, I am," said the Doctor.

A thousand readers threw up their arms and cried out in one voice that shook the heavens and shattered the earth, "What the fuck was that?"
