Mabel gave you a walkie talkie "I'll tell you when to come back!" You nod and set off into the town

As you were walking through the town someone ran up to you, he had white hair which went up. How much hair gel does he use? He also had a baby blue suit

"Howdy! My names Gideon, what might your name be, beautiful?" You couldn't help but blush slightly "My name i-is y/n..."

He grinned at you, he was so cute "well thats a mighty fine name, y/n! Why don't you come to the tent of telepathy and we can talk more"

Your walkie talkie beeped and Mabel was heard on the other side "we're ready! Come back" "ok, I'm coming, Mabel" you replied and put it away

"Sorry, Gideon. I would love to but a birthday party is nothing without the birthday girl"

"oh, well happy birthday and I hope you have a mighty fine birthday!" you waved goodbye to him and head back to the mystery shack

~At The Mystery Shack~

You looked everywhere for them, you went to the backyard and saw it was decorated with balloons and streamers

All of a sudden Soos, Ford, Stan, Wendy, Dipper and Mabel jump out

"SURPRISE!!!" They all shouted, of course Mabel was the loudest

You giggled and then Gideon flew in while riding a giant parrot "surprise!"

You stared at him in shock as he jumped off it once it landed and he gave you a small present

"For you, m'lady" when you opened it there was a diamond necklace which he put around your neck

"Its... Amazing, thank you, Gideon" you didn't think much of it apart from how much trouble it must've been for him to get in such a short space of time

"Its almost as beautiful as you" you saw Dipper's eyes widening

"What are YOU doing here, Gideon?!" He stomped over "I came to celebrate y/n's birthday, is that a bad thing?"

Dipper grumbled and gave you a box which was a little bigger then Gideon's but still small

Inside was a snow globe. "Thanks Dipper" at this point its obvious it was to be nice, the pines family weren't rich so it was nice that he gave you anything

"No problem... Its from all of us..." You smiled at him "its... Nice, Dipper. Thank you"

He seemed aloof and Ford came over "actually, this was sent here. I don't know exactly who sent it, there's just a triangle"

You took the present, knowing exactly who gave you it and unwrapped it. Inside there was a beautiful dress, it wasn't made in gravity falls so Bill must've done alot to get it

(Bish, he can teleport things)

Gideon stared at it. "How... Who gave it to you?!" How do you explain the demon? "I dunno, there's just a triangle here" you showed him the card

A beautiful dress for a beautiful girl

-love ∆

He thought for awhile as you went to put it on

"Triangle... Wait, is i-?!"

You came back out in the dress, you had even found some matching shoes for it

"Who was it..." Gideon watched you, basically swooning in love

You had an amazing party for the rest of the time, you played games, ate cake, it was amazing

Gideon's POV

I walked back in my house and into my room, thinking who could of given y/n that dress

"Wait... Triangle... CIPPHHHEEERRRR!"
