Princess Celestia had long since lowered the sun and Princess Luna had the moon near its pinnacle when Ponyville's various ponies started to sleepily trot away from the tree where Pinkie had started Rainbow Dash's birthday party. They rubbed at their eyes and yawned, bellies full and cheeks tired from all the laughing and music. Throughout the event, Pinkie was vigilant in making sure every-pony had what they needed.
Applejack hopped off the dance floor, sweating and panting. "Phew! I'm plumb-tuckered out. I think it's about time I get these li'l doggies home." She stretched her legs and shook away the stiffness that was settling in.
"I must agree with you." Rarity joined Applejack's side. "It was a fun day, Rainbow Dash. But, Opal needs her brushing and I ache for a bubble bath."
Rainbow Dash gave a tired laugh. "I understand, girls. I'm feeling beat, too. Thanks for coming! I'll see you all later." They left, muttering another 'Happy Birthday' back through the night air.
Fluttershy stepped past as well, "I do think it's time call it a night, then. Angel still needs to be tucked in, don't you my little cuddly-wuddly…" she cooed at her rabbit friend. "Good night, girls."
"Sleep well, Fluttershy." Twilight smiled and turned to Pinkie, "do you want us to help you clean up, Pinkie Pie?"
"Yeah, I can help and it'll go by ten times faster!" Rainbow Dash stood up, fanning out her wings.
Pinkie stood in the middle of the streamers and discarded party cups, giving a deep sigh. "This is always my least favorite part… When the party's… o… ov… ove-"
Twilight put a hoof on her friend's shoulder. "Hey, the party's never really over, y'know."
"Yeah! And, we'll definitely have more! We can't have another one until this one's done with anyway, right?" Rainbow added.
"I suppose you're right." Pinkie gave a small smile.
"Of course I'm right. I'm awesome." Rainbow flicked her tail and smirked.
Twilight conjured up her Magic and had every decoration and used party cup stuffed inside the picnic basket, leaving the area spotless. "I'll recycle all of these tomorrow. I think it's time to get going, gir-" her eyes widened in surprise as Pinkie suddenly thrust her front legs into the picnic basket and pulled out a small pile of streamers and glitter, holding them close.
"Souvenirs!" she cried and snuggled against them.
Twilight and Rainbow Dash exchanged looks of confusion, but let it go. It was Pinkie, after all. They knew to just let her do what she did and accept it.
"Thanks for the party, Pinkie Pie." Rainbow said.
"Thanks for the birthday!" Pinkie said back, her curly pink hair full of confetti.
Seeing Rainbow Dash and Twilight smile as they turned away left Pinkie's heart feeling warm and content. She let out a sigh and collapsed into the cool, dark grass already planning the next fun event for her friends.
