I'll do a female version after this story, for all u Pinkie lovers out there. ;)

"So, you got everything for your sisters surprise birthday party?" Your best friend Antor asked you. He was really excited and nervous for your sister BlueTree's birthday party, which he was going to propose to her at.

"Yes!" You say, for the one hundredth time.

"You have the guest's RSVPS?"

"Yep."

"The presents?" You nod. "The decorations? The candles?"

"Yes and yes!!" You sigh. "I have literally everything we need!"

Antor thought for a moment. "What about the cake?"

"Ye-" you started saying. "-oh no..."

"You didn't get the cake?!" He yelled at you. "(Y/n)!"

"I'm sorry! I'll get the cake Sugercube Corner right now Antor!" You open the door with your magic and trot off towards the place with everyone's favorite sweets.

You come in the building with a ding of the bell hanging above the door. You breathed a big breath, since you ran all the way from your house.

"Hi there!" A cheery voice rang out from the desk in front of you. You look up again and see a happy mare with poofy pink hair, pink body, some balloons for her cutie mark, and blue eyes. "How can I make your day a happy, fantastilisious, awesome, colorful day?"

" 'fantastilisious' ?" You chuckle.

"Yeah! When something's fantastic and delicious!!"

"Like your cakes, Pinkie Pie!" You smile big.

"Thank you!! Anyway, what are you here for?"

"I'm here for a birthday cake for my sister bday party." You say.

"Oh! You must be (y/n) then!" She reaches under the counter and pulls out a 3-layer blue cake with tiny trees and plants. On the top layer, it says in pink: Happy Birthday BlueTree!

"Yeah, I am! How'd you know?"

"Well, I'm helping throw the party!" Pinkie smiled big.

"Really??" She nodded, the smile still on her face. "Awesome!"

You started lifting some bits out of your satchel, but Pinkie refuses. "You can have it."

You were shocked."...no, I couldn't not pay for it!"

She smiles even wider. "No, it's on the house! Your buddy Anton is already paying SugerCube Corner for the other snacks at the party, so, here ya go!"

"Are you sure?"

"I'm positappy!"

"...What?" You chuckle.

"I'm positive and happy!" She laughs, a whimsical sound. You smile, just because of the wonderful energy she gives off.

"Well, then I'm feeling positappy too!" You start walking out, lifting the cake carefully with your magic. Then, you look back. "Thank you so much Pinkie."

"No problemo....yo!" She says.

You laugh and walk out.

*___________________________________________________________*

"Everyone!!" Pinkie Pie shouts at the birthday party. "I see her coming!! Turn off the lights! Hide!"

Antor turns off the lights and we all hide. I do an invisibility spell and turn invisible right where I was. Then, the door opens and BlueTree walks in. She turns the light on with her magic. After that, we all jumped out and yelled, "Surprise!!" We saw the delighted shock on her face.

"Oh my gosh!" Your sister shouted. "You guys!" She blushed in happiness when she saw her boyfriend, and then she ran to him and kissed him. Everyone "aw"ed at the sight while the fillys did a disgusted face.

An hour into the party, Antor flew up to the ceiling with his yellow wings and yelled, "Everyone! Everyone, listen up!" Then, every pony became quiet and your best friend flew down right in front of BlueTree. He kneeled down and held a *bracelet with a diamond on it with his wing. She gasped, hoping she knew what came next. "BlueTree? Will you make me the happiest stallion in the world... And marry me?"

She had joyful tears in her eyes. "Yes!" Antor put the bracelet on her leg and they kissed. Everyone cheered and once they were done, all the girls went up to my sister and congratulated her... Except Pinkie Pie.

"Hi." She walked up to you.

"Hi, great party!" You smile.

"Thanks! I didn't know that was gonna happen so... Yeah!"

"Um....Pinkie?"

"Yes?" She looks at you.

"W-would you like to go out sometime?" You blush and look at the ground.

"Really?" She asked.

"...yeah but you don't have to I mean-"

"That would be awesome!" Pinkie looked so happy. "I actually was going to ask you, so, this is perfect!"

"Wow!" You say where to meet and when and your both smiling.

You didn't know it yet, but you love Pinkie Pie...and you always will.
