"Dipper! You ready to go? We're going to miss the bus!' Mabel shouted from the front porch, dressed in her Shooting Star t-shirt, wearing skinny jeans and her jacket tied around her waist. She finished off by wearing her Converse shoes.

"Dipper! C'mon!" she shouted once more.

"I'm coming, I'm coming!" Dipper said a he hurried down the stairs. He still has his Pine tree hat on his head, with an orange t-shirt and jeans. He ran to the front porch and wore his shoes.

Dipper and Mabel are 15 now, and summer holiday just came around. They are about to visit the Mystery Shack.

"Kids! Before you go I've packed some sandwiches for you!" Mrs. Pine said, bringing two packs of paper bag.

"Thanks mom!" Dipper and Mabel said at the same time.

"Oh, and don't forget to call us when you get to the Mystery Shack!" Mr. Pines said from the living room, drinking a cup of coffee and wearing a robe after shower.

"Love ya both!" Mabel kissed both parents on their cheeks.

"Bye pops! Bye mom!" Dipper said, hugging both tightly.

They both took their sandwiches and hurried out with their luggages. By ten seconds, the twins were gone.

Dipper and Mabel rushed down the street, they only have few minutes left before the bus leaves. Hopefully, they arrived at the station on time.

"Yes! We're on time!" Mabel said and high-fived Dipper. They took out their pennies for the bus fee as they step up to the bus. They found seats available at the first three rows.

"Ah, can't believe we're going back to the Mystery Shack. How long has it been?" Dipper asked.

"Three years, I think? Man, it has been a long time." Mabel replied. "I can't wait to see all my friends! I wonder how much things have changed during these past few years. Especially Wendy…" she giggled as she teased him.

"Quit it Mabel, I moved on. And for real this time." Dipper said.

"Yeah right. Anyways, I'm starving!" Mabel said. Her stomach growled. "I'm starving." She patted her stomach.

"Me too. We should eat." Dipper said. He took out his breakfast wrapped in paper bag, and Mabel took hers out. They took a bite of their thick toasted sandwich.

"Mmmmm!" They both said in unison.

Just then bus started to move forward, towards the good old town of Gravity Falls Oregon. Everything seemed fine. But what the twins don't know is something big is about to happen.

(Author's note: Hey guys! I'm Angel, a BIG fan of Gravity Falls. I saw lots of FanFiction, and decided to write my own. This is suitable for kids, teens and adults too! I hope you guys enjoy my series and wait until Chapter 2~ Coming soon.)
