Pinkie Pie struggled against the ropes binding her to her throne, mewling pitifully from behind a bandanna gag, as Applejack dusted off her hooves with a sense of satisfaction. Twilight shrugged and spoke with an apologetic tone. "Sorry Pinkie, but you'll understand after I tell you what this meeting is about."
"Goodness, Twilight, this seems a bit extreme." Fluttershy looked from Pinkie to Twilight with some concern, but after remembering the time she had Applejack tie her to a chair, she muted any further protest.
"Aw shucks, they ain't all that tight, sugarcube." Applejack backed away from the struggling party pony, hopped up to her place and sat back. "I'll let you go as soon as Twilight says it's safe."
"Twilight darling, won't you please tell us what is going on?" Rarity leaned forward, her elbows on the map table. "We're all so curious!"
Rainbow Dash sat staring into space, moving her hooves around while considering a variation on the Split-S maneuver, using a barrel roll instead of a snap roll. "Uh huh."
Twilight thumped her hoof on the table, bringing Dash to a state of near-alertness. She glared at the easily distracted pegasus and spoke with what she hoped sounded like authority. "We have to perform an important mission for Princess Celestia."
"Oh boy!" Rainbow Dash bounced in her seat with newfound enthusiasm. "Do we have to defeat a monster? Explore a dangerous territory? Spread the Magic of Friendship by any and all means necessary!?" She grinned almost manically at Twilight, anxious for action of some sort.
"Nothing so bloodthirsty this time, sorry. We just have to —" she glanced nervously at Pinkie, who writhed in her bonds "— DISCREETLY... help Princess Celestia pick a birthday present for Princess Luna."
There was a collective gasp, then a silence fell over the room as all concerned turned to Pinkie Pie. Her eyes bulged as she practically vibrated with energy. Her hair quaked ferociously, and the ropes made creaking sounds. The chandelier above started to rock back and forth as small glass and ceramic objects on the shelves clinked against each other. When Pinkie started to make noises like a kettle coming to a boil, Fluttershy ducked under the map table.
A pink explosion soon followed. Fragments of Appleoosa's best hawser accompanied by confetti and streamers rained down on the onlookers. A rocket launched from the throne and burst in pink, blue and yellow above them, and there stood Pinkie, free of her bonds, in the middle of the map table. She inhaled and shouted, "PARTYPARTYPARTYPARTYPARTY!" at the top of her lungs.
If it had not been for Twilight's quickly cast Sphere of Silence, the sound would have blown out the windows and caused short-term hearing loss for those nearby. But as it was, nopony heard a peep except for Pinkie Pie, who sat down heavily, her head ringing like a bell once Twilight dropped the spell.
"Pinkie, this has to be kept quiet!" Twilight frowned at the party pony.
Pinkie frowned back, holding her head as though to still the vibrations. "I have to go on a diet? I don't think so, Twilight Sparkle, and you're one to talk!"
Twilight looked confused. "Not a diet! What?" She involuntarily looked down and poked her stomach, pursed her lips and then looked back up. "Um... I mean we have to be discreet about the present!"
Pinkie's eyes widened. "Why do you want to pour concrete on a pheasant? Is it a stool pigeon?"
Twilight was nonplussed. "That doesn't even make any sense! ...Does it?" She sighed, then cranked her voice up to maximum volume. "WE CAN'T TELL ANYPONY ABOUT LUNA'S BIRTHDAY!"
Pinkie bounded forward and put her hoof over Twilight's mouth. "Sheesh, Twilight! Keep shouting like that and everypony will know about it!"
"Grrrrr!" Twilight shook Pinkie off and took several deep breaths as Fluttershy emerged from under the map table and took her seat. "Thank you, Pinkie. I'll try to be more quiet about it." Subdued snickers sounded from around the table. "Now, who has any idea what Luna would want for a birthday present?"
"Ah take it that books have already been considered?" Applejack drawled, her green eyes sparkling, generating another general chuckle.
Twilight raised one eyebrow in challenge. "Yes. Do you have a better idea?"
The apple bucker shook her head. "Princess presents are not my strong suit, sugarcube. Maybe a new pair of apple-bucking boots or a ten-gallon hat?"
Rarity rolled her eyes. "A new dress, perhaps? But what are her tastes like? We only ever see her in her regalia when she's not at a formal event, and you can't just give somepony an evening gown for a birthday present... accessories? Does she wear earrings?"
Twilight shook her head. "Not that I know of. Celestia and I talked about clothing and jewelry, and she's never worn anything Celestia's given to her. Not even those cute little moon slippers she had made." Rarity huffed—she had worked on those for two days.
"Maybe a pet?" Fluttershy looked thoughtful, considering the petly virtues of various nocturnal creatures.
"For a birthday present? You can't make somepony's mind up about what kind of pet they should have. I should know." Rainbow Dash dismissed the idea and everypony including Fluttershy nodded. "She needs something truly awesome! How about a pair of racing goggles!?"
The rest of the ponies laughed and Rainbow Dash smiled and shrugged. Then all of them turned to their resident birthday expert, Pinkie.
She looked around, plainly upset. "I don't know enough about Luna to get her that extra-special perfect wonderiffic birthday present she deserves! I don't have any problem picking out presents for you guys, but I know you super-well! I don't even have a party-dossier on Princess Luna.” She stared down at the table top, her brow furrowed. “I mean, choosing a super-special birthday present for somepony without having known them well for a long time is tough enough, but we have to figure out what would mean a lot to her coming from Princess Celestia! It's a poser, alright." She stroked her chin, pursed her lips and thought quietly for several moments, to the amazement of her friends.
Spike scratched his head with his claw. "I wonder what her last birthday party was like. I mean, it was a thousand years ago."
Twilight grinned and picked him up. "Spike, you're a genius!" She immediately dropped him in his small throne and turned back to the other ponies, addressing them as Spike got his wind back. "Let's find out everything we can about her last birthday party!"
"How do we do that? Should we just ask her?" Applejack removed her hat and dusted off some confetti that had landed on the brim before putting it back on.
Twilight shook her head. "That's not very discreet, is it? I think we can find out a lot just looking for clues... and can anypony guess what I have in mind?" She smiled slyly, looked around the table.
Fluttershy got the idea and flushed. "Y-You don't mean the Castle of the Two Sisters... do you?"
Rarity clapped her hooves together. "Wonderful! I'm sure we'll find some delightful period party outfits!"
Dash did a quick loop-de-loop. "Yeah! Maybe a monster has moved in since the last time we were there!" Fluttershy instinctively ducked back under the table, then peeked over the edge.
Applejack nodded. "What would be looking for, photo albums? Did they even have photos back then?"
Pinkie Pie danced around. "You know what this is? A full-blown archaeo-partyo-logical expedition!" Her voice increase in pitch and volume as she spoke, so that everypony shushed her at once. "Sorry," she whispered, abashed.
Twilight smiled as she felt the excitement building in the room. "Then that's what we'll do. If anypony asks, we're going to do some magical research, and that's more or less true since friendship is magic, and we're doing friendship research. So Applejack, if Applebloom starts prying, you’re covered." The farm pony winked in response and she turned to address the rest of the team.
"Everypony go get what you need for the trip, except for you Rarity—please only bring what you can actually carry yourself." Rarity glowered and sniffed as Twilight continued, "And meet back here in two hours! Good thinking, Spike! Now let me get our packing list started!" Spike groaned, but smiled nonetheless as he followed Twilight out of the map room as the others walked, flew and pronked respectively out to their homes to gear up.
Two hours later, the group assembled on the lawn in front of the Castle of Friendship.
"Twilight, I know you told me to pack light, but this was really the bare minimum." Rarity was hitched to a small but elaborately-decorated cart loaded with trunks, suitcases and a vanity of all things. "I can't carry it, but I'll pull it."
Twilight sighed. "You do have food and water in there someplace, right?" Rarity nodded. "OK, just don't try to get Spike to carry anything for you, alright?"
Rarity affected a wounded look. "Why Twilight, what makes you think I would I ever do such a thing!?"
Twilight resisted her impulse to roll her eyes and turned to look at Fluttershy. She continued to assert her self-control and suppressed a laugh. "What is that you're wearing?" Padding and plates covered Fluttershy, her pink mane spilling out from under a steel helmet. "Is that... armor?"
"What if Rainbow Dash is right and there's a monster there now?" Fluttershy peeked through the eye slits of the helmet.
"Then you'll probably talk to it, serve some tea, and it will show us to the Legendary Chamber of Clues." Twilight gave her a lopsided grin. "Where did you get it? Can you even fly in that?"
"I borrowed it from Rusty Duster, the museum curator, and um... no, not really." Fluttershy scratched at the ground, feeling foolish. "And I do have the medical supplies." She indicated her saddlebags which bulked alarmingly on top of the armor.
Spike gave Twilight a significant look. Uh oh, I think I'm being insensitive again, she thought. "Well, that's alright, we want to stick together anyway. No need to fly unless you want to, though you may want to take the helmet off to speak with the cockatrice, manticore and hydra for us. But bring it in case of monsters, right?" Fluttershy nodded, smiling, the irony lost on her. Or maybe not. Friends aren't monsters, after all.
Applejack stood with full saddlebags and coils of rope hanging off of her. "Ah'm all set for a week or more if need be."
"I hope it isn't a week, because then we'd miss the... ah... magical event." Twilight looked around to see if anypony was listening.
"Do you mean the part-" Pinkie caught herself "-ial stellar conjunction?" Pinkie looked around as well in a highly exaggerated manner.
"Yes, that's right." Twilight couldn’t help but roll her eyes this time as Pinkie picked up a leaf and showed it to her. "Why are you holding a leaf in front of my face, Pinkie?"
"Look! A bug!" A woodlouse looked up calmly from the bottom of the leaf as Pinkie turned it over, and Twilight rewarded it with a flat stare.
"That's actually an isopod crustacean." Pinkie sighed with relief and put the leaf back, the woodlouse returning to its foraging. "Are you packed? Nevermind, stupid question," Twilight said with a glance to Pinkie's voluminous magenta mane and tail. She looked up at Rainbow Dash, who lazed on a low hanging cloud she had dragged to the castle specifically for that purpose. "And how about you, Dashie? Are you ready?"
A rainbow contrail afterimage glowed in her sight as Rainbow Dash appeared in front of her. "I was born ready!" If anypony could be said to fly with a swagger, it would be Rainbow Dash.
"I mean, are you packed? I don't see any saddlebags." Twilight seemed confused.
"Nah, I'm good. The only thing I need is awesome! And I have enough of that for all of us!" Twilight's mouth flattened out as she prepared an acerbic response and Rainbow Dash laughed. "Wow! You should see your face! Don't worry, Twilight, I have all my stuff stored in the cloud."
Twilight looked up at the cloud, confused. "Oh. Well, OK, but what about when we go inside the castle?"
"I'll just park it. I've got a pack in there too. See Twilight? You're not the only one who can plan. You're just the one that enjoys it the most." Dash smiled as Twilight nodded grudgingly.
"And that brings us to me. Spike, are we ready?" Spike picked up a set of purple saddlebags and put it on her back. He wore a green backpack as well.
"We're all set, Twilight. I've got the folding desk, ink and quills, and a lot of paper. And I found that book you wanted, Pre-Equestrian Linguistics."
Rainbow Dash and Applejack chortled. "That'll prove really useful, Ahm sure." Applejack nudged Rainbow Dash.
"Yeah, you never know when we'll find..." Twilight brought her voice down before she whispered, "Everything You Wanted to Know About Birthday Parties But Were Afraid to Ask, written in ancient Unicornian." Applejack grinned at Dash, having evidently shared the story of her sleepover experience in the old library tree.
Twilight closed her eyes, counted to ten and then opened them, smiling. "Yes, you never know what we'll find. Now let's go, we want to get there by nightfall!"
They fell in behind Twilight and Spike and marched down the road that led into the Everfree Forest. As they did so, Applejack sidled up to Rarity. "Ah sure do miss that old tree, ya know."
Rarity smiled sadly at the sturdy earth pony. "So do I, darling. We need to do another sleepover sometime. All of us, when there's nothing else going on."
Applejack grinned broadly. "You want a rematch on that there pillow fight that Ah won, sugarcube?"
Rarity narrowed her eyes. "If you'll think harder than usual, my dear, you'll recall that I was the victor."
"Eee-nope. Say, how many pillows do you have in that there tumbrel of yours?" She eyed the gilded, jeweled cart that Rarity was pulling.
"It's a phaeton, you troublemaker. And wouldn't you like to know?"
Twilight listened to her friends ribbing each other behind her and smiled, then reached out and picked Spike up with a tendril of magic, plopping him on her back. She levitated a small bag of gems from one of her saddlebags and dropped it between her wings in front of him. "Snack?"
"Gee, thanks Twilight!" The happy crunching noises and giggling conversations warmed her heart as they closed on the verge of the forest. Life is good.
