"I solemnly swear that I am up to no good." Ivy tapped the parchment with her wand and the usual words appeared, Messers Moony, Wormtail, Padfoot and Prongs are proud to present The Marauders' Map. She smiled and opened it. She looked around at the map of Hogwarts, seeing Filch walk near the Gryffindor Tower with his cat, seeing many Prefects on duty. Even Professor Snape, the Potions Master, was probably doing some extra work in his office.

"Ivy, you've been doing that for hours. Go to bed." Marvelle whispered, pulling the blanket over her face. Ivy ignored her.

"There's no teachers around the Slytherin Common Room." She got up slowly, still staring at the map. "Marvelle you coming?"

"What?"

"I'm going to prank some Slytherins." Ivy put her shoes on and stood up.

"Why?"

"Why not. Are you coming or not?" Marvelle sighed and got up. Ivy walked over to her trunk and took out two bottles of glue.

"If we get in trouble-"

"We won't, let's go." The two girls walked out of the dormitory as quietly as they could and ran to the Slytherin Common Room. Ivy glanced at the map, seeing no teachers and looked up at the Slytherin door.

"Did you even think about the password?" Marvelle asked with slight annoyance.

"Of course I thought about the password!" Marvelle raised an eyebrow. "Okay no I didn't think of the password. Slytherins rock?" Nothing happened.

"Wow creative. Blood-traitors?"

"That's meant to be better? Pure-bloods."

"MUDBLOODS SUCK!!!!!" Marvelle grinned and Ivy looked at her in shock, especially when the door opened. "I always wanted to say that. I mean, obviously it's not true. You know." She swaggered in.

"Wow..." Ivy said after a while and followed. She grabbed a bottle of glue and looked around the dark, gloomy Common Room.

"This is so messy..." Marvelle muttered, Ivy rolled her eyes.

"Well put everything back in its place again. Catch." She threw the second glue bottle to Marvelle, who caught it quickly.

"Okay." Ivy grabbed a lamp and glued it back onto the table. She did the same to a bottle of ink and a piece of parchment someone must've left. Marvelle grabbed a pillow and glued it to the couch.

After a while, when they had finished gluing the last books onto the bookshelves.
"Good luck to them." Ivy said as she walked out of the Common Room. She held the map and looked at it again.

"Okay, now if we get caught or lost. I am going to kill you." Marvelle stated.

"Filch is nowhere near us, he's near the Ravenclaw Tower-"

"Really?!"

"Oh he'll be gone soon. Now stop worrying or someone could hear you." Marvelle sighed with defeat and they walked around the castle, making sure not to bump into anything.

"Oh bloody hell." Ivy said suddenly when they were passing the Gryffindor Tower.

"What? What did you do?!"

"Filch is over there. Mischief Managed." She tapped the map and it disappeared. Ivy shoved it in her pockets.

"Now what are we going to do?!"

"Be quiet! Let's just find our way back to Ravenclaw Tower..."

"Going for a nightly stroll are we?" The two girls screamed and turned around. Filch looked down on them, smirking while stroking his cat, Mrs Norris. They gulped. "Oh aren't we in trouble? Both of you will come to the trophy room for Detention tomorrow night. Now back to your Dormitories!" Ivy and Marvelle nodded quickly and ran off.

~~~~~~~~~~~~~~~

"I cannot believe you got me in trouble!" Marvelle exclaimed quietly the next day when they were in the library, doing homework.

"I cannot believe you both snuck out! Again!" Maria added. "It's only the first week and you've got a detention! That's probably a record or something...."

"It doesn't matter." Ivy rolled her eyes. "You wanted to go-"

"You said we wouldn't get in trouble!"

"I said, I didn't promise. Besides you can just not go to the Detention-"

"Oh yeah..."

"I heard Mr Filch will track you down, tell our head of house which is Professor Flitwick and basically scare the living daylights out of you because you don't go." Maria stated. "Then he'll tell your parents."

Ivy and Marvelle glanced at each other and said in unison. "We're going!"

That night, the two hesitatingly headed to the trophy room. Once they were there, they saw Filch and two redhead twins, who looked at them with confusion.

"Looks like we're not the only ones who got detention." Ivy whispered to Marvelle while glancing at the two boys.

"We still got Detention." She replied with annoyance.

"Good you all decide to come." Filch said to all of them. "You'll be cleaning the trophies today." He pointed to all the trophies in the cabinets. Ivy sighed, there was quite a lot.

"Yes..." Marvelle smiled and they all looked at her. "What? I'm not meant to feel happy?"

"Without magic." Ivy and the two boys flinched and sighed. Four buckets of soapy water with rags appeared in front of them. "Be grateful they don't have the old detentions. I could hang students by their thumbs in the dungeons. I miss the screaming." Their eyes widened with horror. "You may start." Filch walked off. Marvelle was the first one to grab a bucket and rag and she immediately started cleaning.

"I worry about you." Ivy said, slightly amused as she grabbed a bucket and rag as well. The boys sighed and followed their example.

"What are you two doing here?" One of the boys asked as he started cleaning. The girls looked at him. "As in how did you get Detention? In the first week?"

"Yeah, wouldn't expect that from two Ravenclaw girls." His twin stated.

"Thanks to you." Marvelle nudged Ivy, who rolled her eyes.

"We were Pranking some Slytherins and Filch caught us." Ivy explained. The other twin dropped his bucket in shock. Ivy looked at him and raised an eyebrow. He grinned and pointed at them.

"You two, do pranks?" He asked. Ivy nodded.

"Yeah why?"

"What a coincidence. We got a detention for Pranking Filch." The other one said.

"What's your name?" Marvelle asked. "This is really confusing, considering you're both twins." The twins chuckled.

"I'm Fred. This is George." The one on the right said. They both identically grinned.

"Let me guess." Ivy started. She pointed to Fred. "You're George." Then she pointed to George. "And you're Fred." Their jaws dropped but they recovered quickly and crossed their arms.

"No. Of course not." 'George' said.

"Yeah yeah sure." Marvelle said, smirking.

"Oh fine. Fred they're too good." The real George said. Ivy and Marvelle grinned.

"Whatever, what are your names then?" Fred asked.

"I'm Marvelle and this is Ivy." Ivy said sarcastically and rolled her eyes. Fred raised an eyebrow.

"Oh really? And you're Ivy as in Ivy Potter?"

"Yes that would be me." She stopped and groaned, before facepalming. "Dammit." The twins laughed.

"Well that failed." Marvelle said, laughing.

"You can't do that if you're not twins." George stated. Ivy grinned and changed her appearance to match Marvelle's. She walked over to Marvelle and looked at the twins, whose eyes widened.

"You're a metamor- a memamop - metmorphagus?" Fred sighed with annoyance. "You're one of those people that can change their appearance!" He concluded. Ivy laughed.

"A metamorphamagus."

"Show off." She laughed again.

"Yes, that would be me. A metamorphamagus." Ivy wiped one of the trophies. The twins and Marvelle did the same, though Marvelle had already cleaned half of the trophy cabinet.

"Anyway what prank did you two do?" Marvelle asked after a while.

"We just set off a Dungbomb." Fred explained. "It was upsetting for Filch for some reason." Ivy laughed.

"A Dungbomb? Like one Dungbomb? That's pathetic." She stated. Fred glared and walked over to her.

"Really Potter? What did you do then?"

"We glued everything to its place in the Slytherin Common Room." Ivy grinned and looked at him.

"That's impressive." Fred shot George a look. "Never mind." George walked away from them.

"Oh and Darling, we also raided Filch's office with Dungbombs. And guess what? He didn't catch us." Ivy said sweetly and grinned. "And we used... Marvelle how many bags did we use?"

"Um... two." Marvelle called out.

"Two bags of Dungbombs." Ivy grinned at Fred's expression. "And look...." She stopped and frowned, trying to figure out his last name. This made Fred grin.

"You're trying to figure out my last name? Take all the time you want." He stated.

"Hang on. Red hair." She looked at his Robes. "Hand me down Robes. Is it Weasel? Wait no, Weasley." Fred frowned even more and crossed his arms. Ivy grinned. "Fred and George Weasley, right?"

"Maybe, maybe not." He shrugged, though slightly annoyed.

"You're those twins that swapped places at the Sorting!" Marvelle exclaimed. Fred and George grinned and nodded.

"That would be us." George took a bow. Marvelle smiled at him.

"I think we're done." Ivy stated, putting the rag back in the bucket.

"Hang on, you missed one trophy up there." Fred pointed to a trophy right at the top of the cabinet.

"Well I can't reach that!" Ivy crossed her arms and frowned at him.

"Fine. I'll do it. Excuse me." He placed the bucket filled with water on the top of the cabinet. Purposely, Fred knocked the bucket gently. The bucket fell and the water spilled on the person below it. Ivy screamed and water fell on top of her, wetting all her clothes and hair, which was changing to multiple colours.

"Oh my Merlin! I am so sorry!" Fred exclaimed, not showing any sympathy.

"That was - that was - you did that on purpose!" Ivy shouted, her hair changing red.

He gasped. "Why would I do such a thing?"

"Gee I don't know! Maybe because you can't accept that your pranks are pathetic!"

"Hey! Do you want another bucket of water?"

"Yes please!" Ivy grabbed her bucket and poured it over his head. Fred screamed and jumped. "Oh I'm sorry! I so didn't mean that!" She rolled her eyes.

"You are - you are - you are so annoying!!" Fred shouted, wiping the water off his face.

"Says you!!"

"Well-"

"Ivy let's go!!" Marvelle yelled and grabbed Ivy's hand.

"Yeah Fred. We really don't want to stay here." George stated, walking over to his twin. 

"Oh fine!" Ivy pointed at Fred. "This is not over!" Marvelle sighed and dragged her away.

"Good!" Fred called back.
