"Did you guys hear that?" questioned Adrien, when they heard what seemed like screams. Arianne and Marinette frowned and approached the window to see if they could spot whoever was in trouble, but they didn't see anything. Instead, they heard more shouting.

"I definitely heard that" replied Marinette "We better scoop this out!" all the class went outside of the room and downstairs, to the entrance. Nino took advantage of the situation to film everything.

"Is anyone here?!" questioned Adrien loudly.

"Can you hear us?!" asked Arianne "Hello?! Kim?! Max?!" then, they spotted goo on the floor, next to Kim's wristband. Marinette had seen the exact same thing when she was in the bathroom, looking for Myléne "This is Kim's, right?" questioned the violinist, showing the wristband to Adrien.

"Yeah, definitely" nodded Adrien. Everyone then started to freak out.

"Calm down, people!" said Arianne, raising her hands up "We have to tell principal Damocles what's going on, and Nino, stop filming!" she pointed out to the boy holding the cellphone.

"Not a chance!" he replied "This is just getting good" then, he saw Adrien sneaking away "Yo, Adrien!" he called, startling the boy, who turned around to look at him "Where are you going?"

"I left Officer Jones's jacket back there. Should probably wear it in all the scenes" he lied, rubbing his neck nervously, before running off. Thiago chose to ignore the fact that there was no Officer Jones's jacket, and instead motioned towards one of the classrooms looking at Arianne, who nodded as they both snuck out. They needed to find out whatever was going on.

Thiago took off his watch and Arianne her beret, and they both left them on the floor, in order for their classmates to believe that they had been taken by whatever was on the courtyard.

Then, they transformed.

"Shall we take a stroll, m'lady?" they heard Chat Noir's voice, talking to Ladybug.

"Can we join?" asked Tigre Blanco, and everyone turned to look at him and at Loup d'Argent, who had just arrived.

"Be my guest" replied Chat Noir, and both girls were surprised to see that Chat Noir didn't have the usual bitter tone he used every time he talked to Tigre Blanco.

"Quadrupled legit!" said Nino, still filming everything "Ladybug, Chat Noir, Loup d'Argent and Tigre Blanco in my movie? This is gonna be sick!"

"Okay, so we all know Hawkmoth is taking another innocent victim somewhere in school" Chat Noir spoke up, looking at his partners.

"Yeah, and the only way to get everyone out of here, is by capturing that victim's akuma" added the wolf girl.

"Exactly" nodded Chat Noir "I love it when you read my mind" she just rolled her eyes upon hearing that.

"We better find this...thing first" she stated "And its prisoners"

"Woah, you did it again!" said Chat Noir, amazed, and his friend couldn't help but smile this time.

"Don't mind me!" said Nino, approaching them, and filming everything "Finding the missing peeps and solving this crazy mystery with the masked quartet!"

Yeah, the name the news reporter had given the quartet had grown on everyone in the city, and everyone called them that now.

"I hate that name" complained Thiago.

"That's what you get when you're a famous superhero!" replied Loup in a sing-y voice.

"Stay together, right behind us!" said Ladybug approaching her classmates "You too, Spielberg" she added, grabbing Nino from the arm and dragging him with her.

They went to the second floor, and found Arianne's beret and Thiago's watch. Chat Noir opened his eyes wide as he looked at his friend's hat with worry.

Then, inside the classroom in which they had been filming the movie earlier, they saw Adrien's shoe on the floor. Now, it was Loup d'Argent's turn to open her eyes wide with worry upon seeing it. She exchanged glances with Tigre Blanco, who looked equally worried about his best friend.

"Anyone recognize sthis shoe?" questioned Chat Noir, trying to stay low, and failing miserably at it.

"That's Adrien's shoe!" replied Nino, filming it.

"That's weird" said Ladybug, kneeling down and touching the floor "There's no pink slime here"

"Yes, there is" said Nathanael, touching the slime on the desk. Everyone turned to look at him, as some tentacles dragged him behind the desk. The piece of furniture then was thrown across the room, and they all saw a giant, pink-slimed monster behind it. 

"Everybody run!" ordered Loup, and they did as told, leaving only the quartet, Nino and Juleka behind.

"Awesome" she breathed out and the monster growled at her, which amazed her even more. Loup d'Argent  dragged her out of the way as the monster threw slime at her. Chat Noir then started to dodge the monster's blasts, as a very speechless Nino filmed all of his movements.

"We better hurry up and find where that akuma is hiding!" said Ladybug.

"All I see is slime" replied Tigre Blanco "Not much else, really" the monster then shot slime at them, throwing the quartet to the floor downstairs, but they landed like pros.

Some of their classmates were hiding behind a wall, and screamed when they saw the monster, which made him grow bigger.

"Fear!" realized Tigre Blanco "That's where he gets his strength out from!" Ladybug and Chat Noir attacked the monster, but Chat Noir got trapped in a basketball ring, full of slime, and so did Ladybug.

"Well, it's you and me against it" said Loup, staring at Tigre Blanco, and they both smirked. It was just like old times "You try to free our partners; I'll distract our friend here"

"You got it" nodded Tigre Blanco. As the girl started to play the shrill melody with her violin, her friend turned into a kangaroo using his special power. He jumped high enough to kick the backboard holding the rim, and breaking it. Then, he did the same thing with the slime holding Chat Noir, and managed to save them both, before transforming back into Tigre Blanco.

Loup was forced to stop playing when the monster threw slime at her, and it didn't get to her by very little. Then, the monster grabbed Alex and went off.

"Did you see how it just left Ivan alone?" questioned Ladybug.

"Yeah, what's that all about?" asked Chat Noir confused, and Ladybug gasped in realisation.

"I think the monster is Myléne!"

"It makes sense" said Tigre Blanco to Loup "Ivan did go after her when she left the classroom crying"

"Where are Sabrina and Chloe?" asked Alya, approaching the quartet, with the rest of the group following behind.

"If we can find a way out of here, we'll find them" replied Loup, and Tigre Blanco gave her a questionable glance. If the found a way out?

He may not like Chloe, and he definitely wasn't Sabrina's best friend, but he did think that they had to save them anyway.

Loup d'Argent rolled her eyes and corrected herself.

"We'll find them one way or another" she said reluctantly, and Tigre Blanco nodded, approving of her phrase. Then, they heard a scream they would definitely recognise as Chloe's, and went off, running in that direction.

But when they arrived to the classroom, they were gone.

"We're too late!" said Chat Noir. Ladybug then crouched, and pointed out to the slime on the floor.

"We can track the monster"

And so, they did.

They arrived to the end of the trail of slime, to find a door, which led into a very dark passage.

"Oh, yeah!" exclaimed Nino, raising his arm in the air with triumph "This is so exciting!"

"Turn your volume down" said Thiago "To about four, please"

"My bad" said Nino, rubbing his neck nervously as they got into the hall, which led to the maintenance room, which was full of slimed cocoons.

"Anybody in here?!" 

"Ladybug, it's me! Chloe Burgeois!" they heard the girl's voices coming from one of the cocoons.

"Don't worry, we'll get you out of there!" 

"Maybe" snickered Loup to Tigre Blanco, who gave her another stern glance "What now?!" she questioned, since it was the second time that he did that "Don't tell me that you wouldn't like to get rid of Chloe sometimes!"

"Like most of the time, yeah" agreed Tigre with a nod "But that doesn't mean that we are just gonna leave her here!"

"Let me have some fun every once in a while!" she complained "Is everyone here?!" she questioned with a yell, and various voices were heard.

"Mr. Damocles?! Alex?!" Ladybug cried, recognising their voices. 

"Nath!" called Loup, and heard his voice inside one of the cocoons "Adrien!" she called to her best friend, but no one answered "Adrien?!" she asked, panicking. Chat Noir hid behind a slime ball to answer as Adrien.

"Yeah, I'm fine!" Loup sighed in relief, and didn't notice Chat Noir coming out from behind the slime ball "Thiag?! Aria?!" he called, worried about his best friends. Both of them hid behind a slime ball, too.

"Oui! Please help us!"

"This is disgusting! Get us out of here!" complained Tigre "Did you find Marinette?!" he added, realising that he hadn't heard the girl's voice inside the cocoons.

"Yeah, we got everyone!" replied Ladybug, putting her thumbs up, just as Tigre's armband flashed.

"Uh...guys? We got a problem!" 

"What is it?" questioned Ladybug concerned, as she approached him.

"I'm about to transform back" replied Tigre, showing her his armband, that only had two paws left.

"Go, we can handle it!" said Chat Noir, and Tigre frowned insecure.

"Are you sure?" he didn't want to leave them alone to fight the monster, but he didn't want to transform back in front of them, either.

"Yeah, go" Loup nodded.

"Okay" he agreed reluctantly "I'll see you on patrol at night!" he gave them a small wave, and went off. He couldn't exactly leave the building, so he had to stay in a classroom until everything was fixed. He felt very bad of not being able to help his friends. That's what he didn't like about using his power. It reduced his chances of helping people when he was done using them, and he hated that. He hated being helpless.

Ladybug invoked her lucky charm, which turned out to be guitar strings. She realised that they could use them to play Myléne's song. In the meanwhile, Chat Noir used his cataclysm to destroy some of the pipes, which made a cage around the monster.

Then, Ladybug started to hand random items from a cart to the students, items which would be useful to play the song.

"No, thanks" replied Loup, when Ladybug handed her a couple of cans "I got my own" she showed her the violin, making her smile as she handed the rest of the things out.

"In case you don't get what's going on here" said the wolf girl, looking at the other students "We're going to sing 'Smelly Wolf'"

"'Smelly Wolf'?" questioned Chat Noir "Seriously?" Loup grabbed a trash lid and showed it to Chat Noir.

"You are welcome to join" she said with a smile, which Chat Noir returned as he grabbed the lid, and made a drum set out of it.

"Okay, everyone!" said Ladybug, looking at the 'band' "One, two, three, four!" she started to play an improvised cello made out of a wash basin and a broom, while she sang 'Smelly Wolf,' and everyone soon joined in.

As they kept playing, the monster became smaller and smaller, until they managed to see Ivan's pin, which he had given Myléne, in its head.

"That's the same pin I gave Myléne!" observed Ivan, when the monster jumped into his arms.

"Then that's where the akuma is" said Loup, and turned to look at Nino "Hey, want an awesome song for the end of the movie?"

"Sure!" said Nino "I'm sure that Arianne will agree!" the hero smiled, and started to play the song that turned the akumatized victims back into themselves. Ladybug de-evilized the akuma, and then she returned everything back to normal with another melody.

Nino had documented absolutely everything, even the kiss between Ivan and Myléne!
