Summerween

A/N: So this isn't going to be full of adventures as this is just an introduction to someone knew

You had gotten up early that day to start helping Mabel look for cute summerween outfits for the kids. You both thought it would be cute to take the kids out and help them get used to the holiday in the summer. "Stan is staying in with Ford, so we can take the kids out! Maybe we can dress up too!" She giggled pointing out some cute Halloween outfits for you as well. "Mabel, I am an adult, I am not going to dress up- oh my god that is the cutest outfit ever!" You yelled looking at a black dress which was splashed in ''blood''. "I love it." You yelled picking up the dress and putting it into the trolley. "There's a matching black suit...for Dipper?" Mabel asked picking it up and smiling at you. "Yes!" You yelled throwing it into the trolley and going through the store. 

Jessica was talking to someone in the bedroom while Jason went to get his dad. "She's been doing this for days Dad." He said taking him up the stairs and listening outside the door. "If I tell them about you, I'll get in trouble." Dipper could have sworn he heard someone reply so he entered the room only to see Jessica looking at him. "I was talking to my imaginary friend Rose." She whispered playing with her top and then looking out of the window. "Guys I'm back!" You yelled entering the house and putting the bags on the table. "Mum!" Jasper yelled rushing down to see you, you handed him a bag and told him to change into the outfit you had picked out for them both. "Hey Dip." You whispered softly kissing him on the lips and handing him another bag. "We're matching." You giggled handing Jessica her bag and smiling. "What's wrong?" Dipper walked off and you bent down to hug Jessica. "My friend Rose, she doesn't like you or dad." You smiled softly hugging her again. "It's okay sweetie." You said passing it off as an imaginary friend and going to get changed for that night.

It was starting to get dark so you and the twins began to get ready, you were worried about leaving Stan and Ford alone all night knowing that those two minds together would probably scare some kids. "Behave." You warned them watching as Dipper walked the kids out of the house. "I mean it, we don't need a repeat of last year." You warned remembering the phone call you had with Pacifica about how he'd scared her kids and they didn't sleep for a week. 

"Trick or treat!" They yelled as you went to the final house on the street. "Aren't you just the cutest." The old lady said looking at Jessica and Jasper who were dressed as Ketchup and Mustard. Mabel thought it was just the cutest and reminded her of her and Dippers peanut butter and Jelly costume. "Who's that?" Dipper asked looking over his shoulder at a little girl who was dressed in all yellow with an eye patch. "Is this a joke?" You asked looking at the girl who seemed to be dressed as Bill including a small top hat. "Rose!" Jessica yelled dropping her bag of candy on the floor and running over to the girl. "You see her too right?" You asked Mabel biting your lip and taking hold of Dipper's hand. "Yeah..." She whispered nervously walking over to your daughter. 

"Mum, dad, Jasper, Aunt Mabel...this is rose." She whispered holding her friends hand and smiling. "Hi Rose." You whispered bending down and looking at her, you couldn't put your finger on it but you felt like you knew her, it could have been just because she was dressed as Bill so you pushed it to the back of your mind. "I'm Y/N." You stated, she ran into your arms and smiled. "I'm Rose."

Arriving back at the shack you saw Ford and Stan laughing on the porch while three kids ran away. "What did you do?" You asked hugging Dipper and watching the twins run inside with Mabel. "Relax, we just did the heart jumping from your chest trick." Ford answered mopping up with fake blood from the floor. Dipper chuckled pulling you into his arms and kissing you. "How about, me and you go and have a horror movie marathon...like the old days." He smirked kissing your neck and chuckling as Stan made a disgusted noise. "We'll watch the kids." Ford laughed pulling Stan into the house. You took Dipper's hand and walked into the extension. "I don't want anymore Great great grand kids!!!!!" Stan screamed as you both shut the door laughing to each other. 

A/N: It sucks, I'm sorry.
