The day arrived at Echo Creek, and the first Marco saw was Star's smug, energetic smirk.
"I believe you need to see the rest of the multiverse." Star stated. "After all, as a good slaver, I should let you know what kind of places I can sell you to."
Marco looked legitimately shocked at the revelation.
"What, do you really think I'm going to keep you as my slave forever?" Star laughed at the idea. "Even we were both capable of living for a long time, that wouldn't change the fact that if you fail to live to my expectations, I'll sell you off the instant I get, even if what I get in return is peanuts!"
The princess forced the guy to come with her to a crossroad, where she took out a golden whistle.
"Dimensional taxi!" Star yelled before blowing the whistle.
A couple seconds later, a portal opened and a taxi came out, which Star and Marco went into as another portal opened. The taxi went through the portal and landed in Uni, where Star and Marco left.
"Alright, welcome to Uni, the potential kingdom I could sell you to in the near future." Star proclaimed as the duo looked around. "This kingdom is ruled by a bunch of bodyless unicorns known as the Pony Heads."
The guy raised an eyebrow.
"I know the fact you never say anything makes this warning redundant, but don't ask." Star growled. "Now follow me, I'm sure the princess should be around he-Oh, there she is!"
The pair went to a flying, light blue pony head with flowing pink hair and blue eyes with star pupils. She was looking at the scenery when Star came up to her and said, "Sup Pony Head!"
However, the flying pony head wasn't surprised. "Hi Star." she said in a monotone...tone.
"Aw, come on, baby horse, you know I like a more energetic greeting than that!" Star replied as Marco went to Pony Head's side.
"I'm not the in the mood to see you, Star." Pony Head bluntly growled.
"But I'm in the mood to see you, and that's the only thing that matters." Star responded before bringing Marco to her side. "Listen, I got this slave called...well, his name doesn't matter right now. And I was wondering, if you'd be willing to...exchange currency for him, you get what I'm saying?"
Pony head gave Star an annoyed glare before sternly answering, "Star, even if I wanted a slave, I simply wouldn't approve of it. And neither would my father, for that matter."
With the rhyme lost on Star, the girl shook her head before stating, "Screw your father!"
"Nuh uh, Bitchfly, this horn ain't made for screwin'!" Pony Head snarled. "How about you go screw yourself with that supposedly powerful wand your family has? Oh wait, I remembered, you're not allowed to touch it!"
Offended by what Pony Head said, veins nearly popped on Star's forehead as she turned to her slave and hissed, "Marco, I'll go get a dimensional taxi so we can get out of this place. And don't even think about hanging out with this...sturdy equine, while I do that!"
With her words spoken, Star stomped out of the place and Pony Head approached Marco. "Listen, I'm sorry you have to deal with a jackass like Star, but I'll let you know: she may act tough, but she's basically useless without you." she told the slave, catching his interest inmediately.
After all, from what he had seen of the girl, while an absolute asshole, she didn't look like somebody who wouldn't function without slave. "And with that in mind, I got a gift for you." Pony Head added.
Pony Head opened her mouth, rolled out her tongue and revealed a pair of interdimensional scissors. The slave took the scissors and put them on his pocket as Pony Head explained what they were, "These are interdimensional scissors, you can cut open a portal to any dimension you wish, but you have to concentrate to go to the right dimension."
Right in that instant, Marco was forcefully brought to the dimensional taxi Star summoned, and as he came in he heard Pony Head's last words: "Star's home dimension is called Mewni! Remember that!"
Marco nodded, the door closed and the taxi drove off back to Echo Creek. During the trip back there, Star handed Marco the gift box Jackie gave him.
"I figured you'd probably want a reminder of your life on Earth if I had managed to sell you, so I brought this with me." she explained as Marco slowly opened the gift. "Since you're staying, you might as well open it now."
Once he opened the gift, he took out what was inside: Jackie's phone number. And, not wanting Star to see it, Marco saved it on his remaining pocket and remained silent for the reminder of the trip.
