Miraculous: A Halloween Spook-Tacular

Part 1

"...And that is why Séline De'Arcoup won" Mrs Celine droned on.
"MARINETTE" She shouted "ARE YOU EVEN LISTENING TO ME".
Marinette was so tired after capturing last nights villain. She was so tired she almost dozed off. She immediately continued writing down notes. After class, a group of people crowded round Nathanaël to listen to him talk about his costume for Mayor Bourgeois' Halloween party. The Mayors daughter, Chloe, had been bragging about it all week saying that she had the best costume.
"I'm gonna show up as a cowboy from the west" He explained. Everyone smiled
"Wow, it's sad just listening to your idea" Chlóe said " we all know that my costume is going to be better than anyone else's". Marinette came over, she felt very sorry for Nathanaël.
"So Chlóe, what's your amazing costume then" Marinette asked.
"I'm not telling you, because you're probably going to copy me" Chloe replied. Marinette scoffed and started chatting to Alya. In the corner of her eye, she saw Adrien walk  through the door with Nino. Marinette immediately jumped and ended up in Adriens arms, she was speechless so she awkwardly smiled. Chloe saw what was going on, so she pushed Marinette out of the way
"Adrikins" She said "I look forward to seeing you at my Daddy's party tonight". Adrien shook of her hand that she placed on his shoulder. He helped Marinette up and smiled back.

When school was over, Marinette rushed home to get her costume out of the closet, she was going as a cat. As soon as she was changed she texted Alya
M: All ready to go for the party
A: Me too, I'm going as the bride of Frankenstein
M: I'm a cat. I'll see u there
A: K, I'm almost done

Marinette walked to the Hotel that The Mayor owned. Big purple lights shone everywhere and music was playing in the background. Marinette saw Adrien walk in too, he was a Zombie. Alya's eyes darted to Nino, who was wearing a Frankenstein costume. Suddenly Chloe came down in the elevator dressed as Ladybug.
"Adrikins" She said "So glad you could make it" But instead of replying to Chloe, his eyes were fixed on Marinette. He thought she was looking beautiful. Nathanaël (wearing a cowboy costume) entered the hotel. Chloe was laughing like mad.
"You look stupid" She grinned "Which dumpster did you find that in" Nathanaël was so angry and sad at the same time. He raced into the men's toilet.

Such anger and sadness all at once,why I must take control. Hawkmoth summoned a butterfly and evilized it.
Fly away my little akuma, and darken his heart.

The akuma landed on his fake gun. Just then, a sinister voice appeared in Nathanaël's head.
"Hawkmoth is my name and The Sheriff is now yours. I am giving you the power to use your gun to turn anyone into an embarrassing slave. In return all you need to do is get Ladybug and Chat Noir's Miraculous.

"Deal" Nathanaël said he immediately turned into The Sheriff. He walked out of the men's toilet, people were staring at him so he shot them with his gun. In a flash, they turned into the most embarrassing slaves.
"Mwuu haaaahahaa" The Sheriff laughed
Marinette and Adrien saw what was going on so they rushed to different rooms.

"Tikki we need to transform" Marinette said. Tikki did what she said and Marinette transformed into Ladybug.
"Plagg, Claws out" Adrien said. Adrien turned into the astonishing Chat Noir. The Sheriff had already turned everyone at the party into slaves except for Ladybug and Chat Noir. 

"You will all pay" The sheriff boomed. Then he spotted them. "Ah ha, I've found you"
The Sheriff shouted at Chat Noir but missed, instead it bounced off the walls. They all ducked.
"Slaves, capture them!!!" The Sheriif commanded. They managed to escape.

"That was close My Lady" Chat Noir smirked
"This is no time for flirting" Ladybug replied "The Sheriff is still out there....
