The Kingdom of Mewni was hosting a Royal Amnesty Ball. Many neighboring Kingdoms with their Royals and their Heirs had shown up, and the whole thing was hosted by King River and Queen Moon. Still, they weren't exactly crazy about being privileged to host the Ball. It seems that everyone but their own daughter was going to shown up since they left her on Earth. Of course, that was there fault.

Moon:"Oh, I wish we could've been able to bring Star home for an occasion such as this."

River:"It's not too late, my dear. We could always go to Earth and pick her up at this moment."

Moon:"No, no. We left her on Earth for her safety and to practice her magic responsibly. I'm sure her guides are looking out for her at this moment."

That, however, was not the case. Instead, all ball-goers stood aside as they saw several large individuals coming in. Much to their surprise, it was Princess Star Butterfly, albeit much bigger than she was before, she and her friends from Earth had more bountiful bodies and were all dressed up in big princess gowns that added to their girth, though still seemed tight. And the handsome courter that was with them, tall, tan, and muscular, not many of them knew him but Moon and River recognized him as Marco, Star's Human friend from Earth, and he was looking so much mature than before.

Eyes popped out of hands and jaws dropped to the floor at the sight of the Heir of Mewni's new look and these new Princesses who looked as beautiful as they were full of life...among other things. Moon couldn't believe what she was seeing as she went over and approached her daughter. Much to her surprise, Star curtsied, as well as the other girls and Marco bowed as a sign of greetings towards the Queen.

Moon:"Star? Marco Diaz?"

Star:"Greetings, Mother. It is so good to be back, and just in time for a regal event such as this."

Marco:"Your Majesty. A pleasure to see you again. It it an honor to be courting your daughter and the other lovely ladies that are with us."

Other Girls:"(in sync) It is an honor, Queen Moon."

This just continued to bewilder Moon more and more. On one side, Star's attitude had been adjusted to be much better and more fitting of a Princess. But on the other side, she didn't know that Star returned, and apparently...gained some pounds? Along with her friends which she didn't even know what to think of. But Marco...where does he fit into all this, she wondered.

Moon:"Star, what exactly has happened to you? You and your friends?"

Marco:"It is nothing you really have to worry about, my Queen. In fact, you may find it quite beneficial."

Star:"Yes. Me and the others here simply gained a higher education in order to become proper princesses."

River:"A Higher Education?"

Marco:"If you don't mind, your Highness, I would like to take your daughter out on the dance floor."

Star:"Oh you. Always such a charmer, Princes Marco."

Moon:"Prince?"

Since when is Marco considered a Prince? Was he actually royalty back on Earth? What exactly is going on here? Moon had too many questions rattling around in her head as she watched her daughter and her friend go out on the dance floor while all eyes were still on them.

Janna:"Oh, how I wish to be Star right now."

Jackie:"Indeed. I envy her for having such a Charming Prince in her arms right now. How I love for him to feed me and play with me."

Brittney:"I would show that I am the most excellent dancer here if given the chance."

Amanda:"Surely, there are other Princess around that would be interested in darlings like us."

Kelly:"Hold that in mind, Dear Amanda. I believe I've spotted the buffet table."

And with that, the other 'Princesses' headed over to a table that had a whole bunch of hors d'oeuvres and quality foods and drinks, which they helped themselves to. A lot of the guests don't know whether to be weirded out or falling in love with how the young ladies are now. Still, they had similar questions that Moon had, such as what kind of Princesses are these? Where did they come from? How are they eating so much? Still, most eyes were on Star and Marco dancing, the Princess of Mewni moving ever so bouncy as she followed her 'Prince's' movements.

Tom was also here. He saw what was going on and walked over to see Star. Got a little upset when he saw that she was with Marco, dancing all over the place.

Tom:"Hey, Star. Can I have a moment to talk to yo-"

But, as Marco spun Star around, her big, dressed-up rear ending crashing into Tom and he ended bouncing away from them.

Star:"Did you hear something."

Marco:"Hmm. Not really, no."

Moon was still bewildered by all of this, but River didn't seemed to mind. He honesty thought that his genes were kicking in for Star, explaining her new look. The Queen still wanted answers through.

Moon:"Something is definitely wrong with our daughter, River. Her mind is not what it should be at the moment. I don't mind the changes, but our lovable, overactive, enthusiastic daughter wouldn't really care for being a proper royal. Not with how she was raised."

River:"Please, my love. You worry too much. The kids are having fun. And young Marco is doing a great job courting her."

But something seemed to flicker in Marco's eyes, which Star merely thought was a sparkle. But it was something else. Since Marco's brainwashing was a bit more paced than that of Star and the girls, it wasn't meant to hold for so long. And thus, he was beginning to notice that something was off at the moment.

Marco:"Mmm...(flickering eyes)"

Star:"What is it, my Prince? Is something amiss?"

Marco:"I'm not sure, but...Star...do you think something seems...different?"

Star:"No. Why?"

Marco:"Well, I just don't know...have you always been..."

He eyes Star up and down.

Marco:"So full?"

Star:"I've just gained a regal figure, is all."

Though he felt like he didn't want it, Marco pulled himself away from Star, much to her dismay.

Marco:"Perhaps I just need a drink...and some time to clear my head."

As Marco walked off the dance floor and headed over to one of the food tables for a drink, Moon took this as an opportunity to talk to the young man and get some answers out of him. If any, he of all people would have better clarity in his mind than the others, and Moon tends to help with clearing that mind of his.

Moon:"Alright, Mr. Diaz. I don't mean to come off strongly, or rudely, but you need to answer a lot of questions I have in mind right now. Because, frankly, what is happening with you and the girls is a bit disturbing."

Marco:"Of course, Queen. I will try my best to answer them."

Moon:"Very well. Can you explain to me how you and the others have gotten so big?

Marco:"It's...kind of hard for me to recall. The last thing I remember was being at St. Olga's Reform School for Wayward Princesses. Star and the others were there too."

Moon:"What? Why would they be there?"

While it has been on her mind to send her daughter to her school, Moon had hoped that being on Earth would be a better alternate solution. But if the kids were there before coming here...

Marco:"Uh...agh...Everything is sort of a blur after I found the girls the way they are now, nearly smothering me before I was pulled away from Heinous and her guards. I don't remember much after that.

It didn't take long for Moon to realize what this meant. The stories that many other Heirs from other Kingdoms have told about that place all seem to be true.

In retrospect, the creepy, prison-like atmosphere of that place and the orderlies that haunt the students down like escaping inmates should have been a dead giveaway that the school was not all that she heard it was.

It was a bit of a shock for the Queen to hear that the kids were victims of being brainwashed. But what about their new looks?

Moon:"That still doesn't explain how they got so big."

Marco:"I believe they may have been given urges to eat a lot of good food. I have no idea why."

And then, Marco recalled what Star was about gaining a regal figure. He wondered if Heinous just for the humiliation or just to add to the mind alteration. But now, it was all starting to add up. Moon wondered if Ms. Heinous, the Headmistress of the school, could be held responsible for the changes to her daughter and the others. Marco himself felt bad that he felt his own brainwashing so easily.

Marco:"I was there to save them...but I failed and fell victim myself."

Moon:"Don't blame yourself, young man. Nobody could have seen this coming. You did all you could, and at least you regained your memory."

Marco:"Right. But how are we supposed to help the girls now?"

Moon:"I'd say we have to talk to the Headmistress about this. Messing with my daughter is considered a capital offense."

And that is when, as if right on cue, Ms. Heinous had shown up with Gemini and had spotted the girls continue to embrace their insatiable appetite as well as the Princess Mentality if the flustered princes they were leaving in their wake were anything to go by. Everything was working out as the twisted Headmistress intended. But she knew that she would have to deal with the Queen as well, as Moon headed over to see her.

Heinous:"Ah, Queen Moon. To what do I owe the pleasure?"

Moon:"You have some nerve showing up. I have been tempted to send my daughter to your school for a while, but after seeing what you have done to her, I have every right to see you locked away forever."

Heinous:"So, you know. But I have merely been doing my job, to ensure that all students at my institution come out as mature, regal, and proper heirs to their Kingdoms. Their new appetites and figures are just a bonus."

Moon:"You brainwashed them! Made them into something they are not! I would never have wanted this, nor would any other ruler I know for their heirs."

Heinous:"What's done is done. The lessons I've implanted in their minds, they will never forget. You really should be thanking me, Your Majesty. Your daughter now has everything she needs to be a proper Queen someday."

And with that, Heinous takes her leave, just as Marco walks up to back Moon up. This was a difficult situation they found themselves in.

Marco:"How are we going to get the girls back to normal?"

Moon:"I do not know. But we must think of something fast, or this could be a huge embarrassment on many accounts."

She gestures to the girls having at it at any remaining delicacies that were supposed to be for any entire Ball Room full of guest. And she was pretty sure they were getting bigger. Though they ate with manors, their gluttony made them eat vigorously. Star was the biggest, Brittney was a close second, and Jackie, Janna, Amanda, and Kelly were following them close behind in terms of size. Their dresses were stretching out and flab was nearly everywhere on their person. After they helped themselves to every last scrap of food that was left, the girls decided to congregate in one of the Halls of the castle. Aside from food and being all regal, the only other thing that was on their minds was their 'Prince', Marco. They were brainwashed into being into him, so they couldn't help but think romantically of him.

Kelly:"Prince Marco is such a charmer for courting us. If anyone one of us should get the chance to marry him, I may as well be me."

Star:"You? Why you? I just danced with him. If anything, he would be perfect as my future King."

Janna:"I have known him longer than any of you!"

Jackie:"Marco has always been into me! I'm his dream girl!"

Brittney:"Please! I'm rich! I can give him everything he wants for the rest of his life!"

Amanda:"D-Does it really matter who Marco goes out with?"

All:"(in sync) Yes!"

The girls continued to argue until Marco showed up with Moon. Immediately, when they saw their 'Prince', they gathered around him, lovestruck and swooning over him. they were clinging to his arms or rubbing his shoulders, happily saying that they were do anything for him.

Star:"Oh, my prince! We were just thinking about you!"

Jackie:"You look tense! How's about I give you a rub down?"

Janna:"No, I will give you a rub down!"

Amanda:"I have nothing to rub!"

Moon:"Alright, alright, enough! Girls, let go of Marco and calm yourselves."

The girls did exactly that and curtsied towards the Queen.

Girls:"(in sync) As you command, your majesty."

Star:"As you wish, mother. Forgive us, we just can't help but lovingly cherish our Prince!"

Marco:"Star, you and the others have been brainwashed. By Ms. Heinous! She did this to all of us!"

Star:"Well, of course. She did it for us."

Jackie:"Gave us a better clarity in life."

Janna:"And revealed an undying love for you."

Brittney:"It's what we live for."

Amanda:"It's why we embraced this."

Kelly:"For you, our Prince."

Girls:"(in sync) We are proper princesses. We embrace the princess mentality and regal figure."

Marco:"...Yeah, this isn't working."

Moon:"We have much work to do in order to get them back to normal."

And it'll take some time before they are able to do so...
