A kingdom in trouble and a rampaging MonStar and people say that Monday's are bad.

Marco was trying to catch up to the flying princess hoping what she has plan won't cause any harm to the people.

"C'mon Star, give me a break here, I'm running on two normal feet." He said as tied to keep up with her, he then saw her head towards the school,

"Great what does she want there?" He asked himself, till he heard boyish yelling. He then went over to find the courtyard completely covered in some kind purplish webbing as he journeys further into the chaos as he did he felt something grab his hand, He looked and saw Brittany Wong.

"You!" She said.

"Brittany, where's S... I mean that monster?" He asked, he felt a sick calling Star a monster, but he didn't want her to get the blame for this.

"That was your friend wasn't it, well that freak just came flying took my weekly date and then this thing flew out of the sky and took him from me and headed there." She then pointed at the gymnasium. Marco then went over to the gym, but as he did he sense that something was wrong as he got closer he saw the doors bang open and one of the male swimmers came running out, but then that same webbing came out of his prison and started to pull him back.

"HELP ME!" He yelled as he pulled back into the darkness and the doors slammed closed, Marco then sighed and steeled his nerves as he entered the gymnasium. Once inside he saw the mess that it was in, purple webbing and what looks like cocoons, Marco soon heard a hissing sound he turned around to find nothing, he then looked around.

"Star? Are you here?" He whispered, just then he felt someone grab his arm.

"Hey! Man You got to help me, that thing is crazy!" He said, then he got a better look at Marco and retracted his hand. "Oh it's you, oh god you must have brought that freak here!" He said.

"Do you want me to help you or not?" Marco asked.

"Right sorry, sorry just get me out of here!" He said. Marco then pulled on the web till he stopped him. "Stop if you mess with this stuff, it'll find us." He explained.

"Well, what do you want me to do!" Marco said.

"LEAVE MY BOYS ALONE!" Marco then looked at the guy in from of him and gulped, Marco slowly turned around to see purple heart-shaped eyes looking at him, he then felt something hit him sending him flying back outside, Star then crawled out of the gym, she looked more monstrous her feminine features were gone she was just a complete lizard monster on all eight of her limbs.

"Star, it's me Marco, your friend?" He said. Star then lunged at him and grabbed him by the shirt and tossed him towards a wall, she then went over to him and grabbed him by the hoodie and started to drag him back to the gym, but she soon felt something slimy around her torso that tossed her off. After she shook it off she looked over at Marco and saw that his tentacle was out and his head down.

"If you're not going to listen, then I guess I'll just have to beat you till you come to your senses, Star!" Marco then stared at her with a malice.

"DON'T GET IN MY WAY!" She yelled as she lunged at her friend, Marco then coiled his arm and captured her and sent her flying, but her wings helped her stabilizing her flight. Marco then stretched his arm towards her and wrapped it around her body and with one strong pull he brought her back to the ground. Marco then tossed her back to her nest, She then started to charge towards him, Marco then swatted her away with his tentacle, he then grabbed her tail with both arms and started spinning her and tossed her into the sky, she soon fell back down and slammed into the ground, Marco then pins her with his monster arm.

"Are going to listen to me now!" Marco yelled, Star then opened her maw as wide as it can as snaps onto Marco's arm, He hissed in pain, she then started to pull on it, getting him off of her and started trashing him around.

"St-Star, s-s-stop!" Marco complained as he was being ragdoll'd, it soon became too much and he was sent flying into a classroom.

"Ouch! Everything hurts, except my...ahh shit!" Marco looked and saw that his arm was gone, he looked over saw that Star was devouring it.

"Well, that's sucks." He said as he got up and grabbed and started trudging towards her, he picked up a stick and she saw him. "Come on! I can still fight Star!" He said, Star then looked at him and started to charge forward, but as soon as she got close enough Marco fell over and Star stopped in her tracks and saw, Marco faint from the pain. She grabs him and takes him to the nest.

-Awhile Later-

Marco groans as he wakes up from his bout with Star, he looks around to see that he was captured.

"Well, this sucks even more." He said as he tried to break free, but as he did he heard growling, he looked up and saw Star resting beside him. "I need to get the hell out of here." He said

"Oh, there's no need to do anything." Marco looked up saw Glossaryck eating out of a pudding cup.

"Hey, your that glossary guy." Marco said.

"Um, my name is Glossaryck and you don't have to worry about anything because she should be turning back to normal soon after she lays her egg." He said.

"Wait! She was pregnant!?" He asked.

"Oh no no, this is just something the females of her species does every mouth, they lay an egg to keep them fertile, but this happened the same time as her mewberty; so it was a little unpredictable."

"Mewberty?" He asked

"Oh yes Mewberty is a phase that Mewman teenage girls go through which is the equivalent of your Earth's puberty, but much weirder and since Star is a hybrid there was no telling what would have happened... Until today that is." He said.

"Is their a way to change her back?" He asked

"Kid, this, like life, is like a runaway port-a-john, hot, fast and filled with shit." He said confusing the boy. "By that I mean, nature can't be stop, just let run its course and she'll probability change back.

"What do you mean 'probability'?" He asked.

"Well I could tell you but I need to get out of the splash zone cause those eggs come out really wet." He said as went back into the book. Star then started to moan and groan, Marco watched the pain that she was in, but what really caught his eyes was that she was shrinking, she soon started to hack something out, Marco watched in disgusted as she continued hacking, Marco saw that he body was changing back to normal after a few minutes Star was back to her normal self, she then gave one last hack and out came a large egg. Star then stood up straight and looked at Marco with a blank look, Marco blushed as he could see that Star has changed, he could see that her body had changed, her breast had expanded to a c-cups and had gained some curves as well and she still had her wings, but they were just smaller.

"Star?" Marco asked as she got closer to him, her eyes were half lidded and she had a smile as she got closer, she placed her hands on his cheeks.

"Marco~." She said as she kissed him shocking the boy. She then broke the kiss and fainted onto his chest.

'She kissed me, Star kissed me; Toffee is going to kill me.' Marco thought as Star fell to his chest.

-Meanwhile-

"How are things with Mewmens?" A voice asked

"Not bad sir, the Johansen are fell for our "declaration of war" and is playing right into our control and I just learned that she laid her egg." the servant said. A pair of white teeth on a figure made a smirk.

"Perfect, get me her egg before they devour it or worse." He said

"Yes Master Tom." He said before leaving him. Tom then went to mirror and saw both Moon and Toffee struggling to protect their kingdom.

"Now that that's done, time to offer my 'services' and finally I'll be one step closer." He said as he left to "help" the King and Queen of Mewni
