Nighttime was falling upon Ponyville. Pony's shuffled off of the streets and into their houses. Twilight Sparkle walked down the streets of the town on the way back to her house. She noticed that almost all the lights were off; save for one house. The house in question belonged to her friend Pinkie Pie.

"Now why is that silly pony up so late?" Twilight said to herself. She walked to the door and knocked with her hoof. Pinkie quickly opened the door.

"YAY TWILIGHT'S HERE!" She joyfully shouted. Twilight jumped back when she saw Pinkie. Her eyes were bloodshot, her mane had hairs sticking up in all sorts of places, and she had the creepiest smile Twilight had ever seen on her face. "Come on in you're just in time for the party!"

"Party? What party? Everypony in Ponyville is asleep."

"Oh it's only a small party. Me and Gummy are the only one's here. But now you're here too! Come on in! The more the merrier!"

Twilight nodded her head. "Pinkie Pie, I know you love to throw parties and all, but don't you think it's a tiny bit late for one now? You should be off to sleep."

Pinkie laughed. "Oh who needs sleep? It just takes away time for parties!" Pinkie trotted quickly into her house and picked up a pin. "Come on let's play pin the tail on the pony!" She tried to put the pin on a poster of a pony but missed completely. "Whoops."

"Pinkie," Twilight asked concerned. "How long have you been awake?"

"About three days! Isn't that great? I've been partying nonstop for three days. Three extra special days of super-terrific-ultra-cool-nonstop partying!" She ran all around the room rearranging the various party snacks she had laid out.

Twilight walked into the house and put her hoof on Pinkie's shoulder. "Pinkie, sweetie, you need to go to sleep."

"But…"

"I don't care how much you want to party. You need to go to sleep."

"But I keep having nightmares…and I'm afraid to go to sleep now."

Twilight smiled. "Oh I see you've been having nightmares. There's nothing to be scared of, nightmares aren't real."

Pinkie looked down at the floor. "Actually…"

"Don't worry about a thing. When you wake up the nightmare will be all over. Now you need to get some sleep Pinkie. Goodnight." Twilight walked out the door and back to her house.

Pinkie sighed. "If only that were the truth." She looked at Gummy, who was equally as worried as Twilight. "She's right Gummy, I need to go to bed." Pinkie got put on her most comfortable nightgown and fluffed her pillows extra soft. She took in a deep breath as she laid her head down and shut her eyes. Sleep was able to befall the pink mare very quickly after its rather long absence from her. But unfortunately for Pinkie the presence of sleep also invite something much less desirable to her mind, and Ponyville. After a few hours she jolted upright.

Applejack woke up in her room. She checked the clock on the wall. It was quarter till 6 in the morning. She sighed to herself. I was wintertime and there was no work to be done on the apple orchard. She knew she could have slept in, but she just couldn't fall asleep. So she figured she would just go make herself breakfast then find a way to entertain herself till the rest of her family woke up.

But when she walked to the kitchen she saw Pinkie setting up party decorations and laying snacks out. "Oh great you're awake Applejack." Pinkie said when she noticed her. "Come help me set up the party."

Applejack gave Pinkie a funny look. "Uh Pinkie, sweetie, what on Equestria are you doing?"

Pinkie hung a streamer above the sink. "Throwing a party for Granny Smith."

"Her birthday's not for another month."

"I know, but she's been such a great pony. She's been kind to us all, made absolutely wonderful apple pie, and she's raised one of the best friends I've ever had. I just have to throw her a party."

Applejack smiled. "Well that's mighty sweet of you Pinkie. You know what, you're right. Granny Smith does deserve some appreciation. Hold on here a second Pinkie, I'm gonna go wake up Big Macintosh and Apple Bloom." Applejack trotted back to her siblings' rooms while Pinkie started to rearrange some of the furniture.

Pinkie looked in the mirror and saw her hair starting to get flat. She instantly shoved a ton of happy and silly thoughts into her head and it regained its puff. "No bad hair." She said. "We need to be happy for today." But Pinkie found it very hard to try and be happy knowing what was going to happen today.

After half an hour the entire farm house was set up and ready for Granny Smith. They waited until she woke up and walked down into the kitchen. Pinkie, Applejack, Apple Bloom, and Big Macintosh all jumped out and yelled "SURPRISE!"

Granny Smith smiled. "Well now, I thought my birthday was next month."

"It is Granny," Applejack explained. "But Pinkie here was so eager to throw you a party to say thanks for being so great."

"YEAH!" Pinkie shouted as she bounced over to Granny Smith. "You're such a wonderful pony!"

"Eeyup." Big Macintosh said in agreement.

"So we're going to spend the whole day with you and play games with you and make you so super-extra happy!"

Granny Smith smiled. "Well this is such a pleasant surprise." The ponyies then had their wonderful day with Granny Smith. They listened to her tell stories of what it was like when she was a filly; then they baked a pie with her and ate it; then they all read special poems that they had prepared about her.

When the sun was just about to set, the Apple family decided that the party had gone on long enough. Pinkie looked at the time and gasped.

"Thanks for the wonderful party Pinkie dear." Granny Smith said.

"You're welcome. I got to go home now." Pinkie walked to the door and turned back to the Apples. "See ya later." She trotted out the door and down the path back to Ponyville. Before she got too far from the orchard she heard a scream coming from there.

"SOMEPONY GET A DOCTOR!" Applejack screamed. Tears fell from Pinkie's eyes as she walked home.
