Gravity falls high school

"Hey Pinetree!" Bill called out walking to Dipper who is looking through her locker.

"Oh hey Bill!" Dipper greeted back "What you so excited about?" She asked shyly.

"Me and Veronica are going to prom together!" Bill said but then looks crestfallen "Are you going?" He asked making her heart jump.

"No! No no no!" Dipper rambled being nervous "Why would I go to stupid prom alone when I could practice the tuba? Yeah that's way more fun!" She said rolling on her heels.

"Aren't you already good?" Bill asked "In my opinion that is but you can still go y'know?" He said rubbing his neck.

"That's okay I have a lot of homework to do anyway." Dipper lied then realized something "What! your still with pyromaniac Veronica?" She asked perplexed.

"Oh yeah she's a fireball all right that's why I named her Pyronica!" Bill said proud of himself.

"Nice Bill. But you guys have nothing in common except your both popular." Dipper said.

"Well if you can keep a secret I've been thinking out dumping her if someone else came along I liked more than her." Bill told Dipper who's smiling wide at the thought of them together.

Later

"Thanks for the ride Mabel!" Dipper said to her twin who making out with her boyfriend and gave Dipper a thumbs up. When Dipper entered the school many stopped to look at her beauty.

"Woah! Who's that? No way is that Dipper? She's hot! Beautiful!" Many boys and girls complimented her making her blush as she walked up to Bill and his pink haired and pink dressed date.

"Mason?" Bill noticed her walking up to him and something inside him walked up to her and marveled her beauty "You look heavenly." He stared at her.

"Thanks Bill." Dipper said being a midnight blue dress with sky blue sparkles, golden earrings matching necklace and bracelets, white heels, and had her long hair down with some sparkle in it.

"Wanna dance?" Bill managed to say and Dipper nodded so they danced the night away till they ended it with a kiss. Meanwhile Pyronica was busy throwing a fit and caused a small fire.
