"No, those aren't the rules of this game," the alien says, furious at them for trying to pull this, "only one team can win."
Velma looks at the people around her. Each has a different idea, it's her turn to dictate this though. She can see everyone's next move, including the aliens. This could be the key to victory.
"Ax," Velma says, looking at the ginger from the other team, "go for it!"
Wendy smiles as she tries to put her ax to good use. She chases around the alien. She isn't sure what she is hoping for but it's better than standing there only wishing for a victory.
"Purple, do it!" Velma commands and Pacifica looks at the nerdy girl before following her demand. She rips the necklace off her neck. The small beads scatter across the floor and the alien trips as they are running.
"Go for it Daph!" Velma tells the girl next to her. She wraps the alien in her sash so they are unable to use their hands.
"Now, let us go!" Dipper demands of the alien.
Velma raises her eyebrow at the boy before continuing his statement, "we can conjure anything we wish, so it would just be easier if you could just let us out."
"Never!" the alien spits in the teenager's direction.
"Fine," Soos shrugs and snaps his fingers.
He throws his summoned object at the alien which traps it. It was the same cube that had gotten the two teams into this mess in the first place.
"Good job, Soos!" Wendy cheers.
Everyone else cheers along too. They are free, they can go back to their dimensions.
"Hang on!" Shaggy says, with a snap of his fingers a party appears, "if you guys have nowhere else to be, I think it would be a pretty good time to celebrate."
"Let's do it!" Mabel agrees.
The two teams get to know each other better as the music plays with them. There is good food, balloons, and anytime they want something else, it is there from a snap of their fingers.
Velma and Dipper can get along without the stress and competitiveness of a challenge. Pacifica and Daphne mirror each other in too many ways and wish there was a way they could stay in touch across dimensions. Fred and Wendy are civil as Wendy explains how simplicity is key, Fred talks about some of the strategies he knows too, Wendy is fascinated overall. Scooby, Shaggy, and Soos, could all be best friends if in the same dimension, they are all so similar with their chill personalities.
Mabel, the ball of sunshine she is, wanders from group to group, she doesn't feel like fits in anywhere. She tries not to let it bother her because she will miss her newly made friends.
"What's wrong Mabel?" Dipper asks his twin.
"I'm going to miss them, we've only known them for a few hours," Mable explains.
"Yeah, but we have to get back. Grunkle Stan and Grunkle Ford are probably worried about us."
"You're right," Mable agrees, "as always."
The teams part ways with sad goodbyes. Each team opens a portal back to their world. They are both happy to return to their familiar scenery but part of each of them can't help but feel they are missing something. The other team had been a feeling they shouldn't have gotten used to. They would always have memories of their interdimensional gameshow.
