Principal Skeeves thought he could have a good day. The first day was usually busy, but it was problems he could either hand over to his secretary, or put off until a little after it was necessary. That's why, when he saw the top of a blond head with devil horns looming outside his office window, he made like a fire drill and dropped to the floor. But it was too late.

"Oh, Principal Skeeeeeeeeeves," Star Butterfly sing-songed.

"I'm not-" he adopted a squeaky tone, "He's not here right now! Come back later!"

A boot forced itself into his door, tearing it off its frame. She smiled cheerily at him as she made her way over the fallen door, a small green child in tow. Skeeves stared at Marco in betrayal as he, too, came in behind Star. Star was the first to speak. "Oh, Skeevsy, your magic voice-changing beans don't fool me. I'm an expert at recognizing disguised voices."

"S-Star Butterfly! Ohoho. So... So clever," the principal forced himself to say, gripping his tie like a lifeline. He readied himself for the worst. "Now, what seems to be the problem?"

"Oh, Skeevsy-Weevsy, nothing's wrong, hahaha!" Star said reassuringly. "Silly. I was sent here by Ms. Bitters."

"Oh," Skeeves replied with a frown. Ms. Bitters had just transferred from Skool Elementary School after a hot glue incident that left her incapable of tolerating small children. He knew Star wasn't in her class- he kept Star with Skullnick because she could handle her. But then, Star had a habit of being in places she didn't belong and causing havoc. "Oh, not to worry, I'm sure I can reason with her on the- err- issue. Nothing to worry about. I am very busy today, can't handle that situation right now. You can go now, and I'll tell her-"

Star held up a hand. "Oh oh oh! Wait! This is Peridot. She needs to be indicted as a fellow student!" The green child moved forward, hands behind her back as she haughtily inspected the room. "Mmm. This isn't quite what I expected," she said.

"Oh God, there's two of them," Skeeves whispered to himself. He tried to not look like his worst fears were affirmed. "Is this child, errr... Do you have any papers?"

"Papers?" Peridot repeated uncertainly. "No one said anything about papers-"

"Yet!" Marco suddenly cut in from behind. "This is Star's... Uhhh... Sister!"

"Sister?" Peridot repeated, confused.

"Sister!" Star said, and grinned as if Marco just told her she could indeed keep the stray puppy. Marco already felt regret for his decision.

"Yes, sister," Marco continued. "You see, she's from Mewni, like Star, who is her sister, but she was sent off to... Saint Olga's Reform School for Wayward Princesses!"

Star screamed, and Principal Skeeves scrambled for cover at the sudden noise coming from the volatile princess. He cames out of hiding when she tapered off. "Saint O's," Star whispered in horror, and visibly shuddered.

"I did what now?" Peridot said, mildly annoyed that she wasn't being filled in. "State Organs?"

"It messed her up a bit," Marco cut in. "She can't even remember the name of the place. That's why we need to have her here."

Principal Skeeves glanced back and forth between Marco and Star. It was too early in the school year to say she was too late for registration. "Weellll, I can't do anything without any papers. And I really need your parent's approval before I can-"

"That's fine," Marco said, calling his bluff. "We can wait here for Star's parents. They're royalty, so it might take a reeeeaaally long time for them to come over here. And I'm sure they'd be so happy with the interruption. Kind of like during that parent-teacher conference last year when Star's dad came through the roof with a battle ax-"

"Welcome to Echo Creek Academy, Star's sister!" Principal Skeeves said hastily, shaking Peridot's hands.

"Uhhh... Okay," Peridot said, once again lost in trying to understand the illogical intricacies of human culture.

"She'll need a guide," Marco added. "And not me. I already have Star. It would have to be a freshmen like her."

Principal Skeeves sighed. "Yess, I guess you're right." He opened his files on the incoming students of Echo Creek before settling on his decision.

"Dipper Pines to the office, please."
