Star stepped back after being gently hit by Dipper but didn't really care. They continued to run. Mabel and Dipper knew the forest like the back of their hand and they dodged almost all of the obstacles, but Star and Marco had a little trouble. If it wasn't for Marco's karate classes and Star's experience in fighting monsters, they would have fallen 15 times by now.
"Careful! There's a tree stump ahead!" Dipper yelled back at Star and Marco. Each of the four jumped over the stump one my one starting with Mabel, then Dipper, then Star, and finally Marco.
Marco turned back and yelled, "HE'S GAINING ON US!" With his voice cracking a lot. Bill started laughing meniacally. "Yeesh. I really need to get that guy some friends." Star said to herself. "I can hear you, y'know." Bill yelled and he teleported Star right in front of him. "Let her go!" Marco yelled at Bill and tried to punch and kick him but Bill was floating too high for Marco to touch him.
He went floating off with Star struggling in his hands and the possessed Pacifica was floating behind him. "Marco!" Star yelled. "Heeeeeelp!" She kicked Bill one last time and that made her drop her wand. "Nice try blondie but you're not getting out. Not while I have you." And Bill flew off out of Dipper, Mabel, and Marco's sight.
"We have to get her back!" Marco yelled pointing in the direction that Bill flew off. "But how? We're no match for Bill. We have been able to defeat him before but I used the journal and I know there isn't anything in there about saving a hyped up on sugar, magical princess from another dimension." Dipper said and he threw the book on the ground. Mabel looked over at the smashed up kart.
Mabel gasped. "Soos!" She yelled.
"Soos?" Dipper and Marco questioned as they looked at each other.
"Soos! He can fix up the kart so we can catch up to Bill." Mabel thought. Dipper thought about it for a second but then said, "or Stanly can help us. He was the one who wrote about Bill! He could be way more of a help to us than the journal."
Mabel agreed and they were off to the Mystery Shack.
Once they had reached the Mystery Shack they were out of breath. "That. Was. Way. Harder. Than. I. Expected." Dipper said taking breaths between words. "Woah, did you three get run over by a pack of squirrels?" Stan joked as he let out a loud, but short, laugh. "We need to talk to your brother." Marco said to Stan. "He's upstairs in the living room." Stan replied and the three were off.
Once the three had reached the living room, Stanly waved. "We need your help! We lost Star to Bill Cypher!" Mabel yelled. "Bill Cypher!? This is bad you guys. We can't let him take her anywhere past the borders of Gravity Falls!" Stanly exclaimed. "Well that's gonna be hard because Bill is taking her to Mewnie right now." Marco said calmly. "WHAT!?" Stanly yelled.
