Gravity falls: A strange encounter

New girl

it was 6:37 in the morning. Mabel was sound asleep, Mabel dreamed of herself Dipper and Wendy on sugar island with candy dogs and kitten fists. Dipper on the other hand was having a nightmare. He was being chased by gnomes, Gideon, Vampires, and a werewolf Wendy. He tossed and turned in his sleep. Stan on the other hand sat outside the mystery shack waiting in a dim light. He had been sitting for hours thinking they'd never come when finally he spotted some head lights turn toward theystery shack. Stan swatted away a mosquito ad he stood and the car pulled to a stop.

A woman stepped out she looked around 40 with brown hair and streaks of grey in it. She wore pants and a white blazer with a grey scarf. "You take good care of her Stanford." The woman scolded. "Relax Samantha I've got it covered. I've got the twins here too she'll be fine." Stan crossed his arms. "Rosalina come on." The woman said, the door closest to Stan opened and out stepped his niece in a hoodie, jeans, and red high top converse with long brown braids and bright blue eyes. "Grunkle Stan!" The girl jumped up and ran to hug her uncle. Samantha got her grandaughters bag out of the car. "Hey you little Recker! Go ahead inside. I'll meet you in there." Stan patted Rosalina on the back and she went inside. "Remember Stan I have custody of this little girl. If she gets hurt I WILL sue you." Samantha looked angrily at her brother. "Yeah yeah whatever, see you later." Stan said as Samantha shoved Rosalina's backpack at him. Samantha got in the car and drove away.

Stan took a deep breath and opened the door to go inside. "Hi Grunkle Stan." Rosalina smiled. "hey Champ." Stan smiled at his niece. "This summer I've got the twins over with me, do you'll have someone your age to hang out with." Grunkle Stan noticed Rosalina smile. "I've got your room set up. Have you slept at all?" Stan asked. "The entire car ride." Rosalina smiled. "Good. Go put your stuff in your room." Stan looked at Rosalina before kneeling down and giving her another hug. A few seconds into the hug Dipper's scream rang through the shack, followed by Mabel surprised one shortly after. "Hoy Belgian waffles!" Stan yelped, he let go of Rosalina as they bolted up the stairs. Stan threw open the door to find the light on, Dipper breathing heavily and Mabel looking at Dipper. "What happed kiddo?" Stan asked. "another Nightmare." Dipper sighed. Stan looked intently at his nephew. "its ok. I've got a surprise. "kids. This is your cousin Recker." Stan placed a hand on Rosalina's back. "Hi." Rosalina smiled. (just to clarify. Recker is Rosalina's nickname) "Hello." Mabel yawned. Dipper didn't say anything
