The four squeezed under the invisibility cloak. It seemed to have been shrinking lately. It's been very hard to fit four 16 year olds under one sheet. They shuffled through the halls until they came to Slughorns office.

"Alohamora," James whispered. They all shuffled into the room and locked the door behind them.

"Why are we here again?" Remus asked.

"Love potion for lily." Peter chuckled.

"That'll never wo-" suddenly Remus was cut off as he and Peter tripped and fell face first into a fountain in the corner of the office.

"Why didn't we turn on the lights?" Remus whined.

Sirius and James were laughing hysterically at Remus and peter's misfortune. They stepped into the fountain to help them up.

"As I was saying," began Remus, soaked in purple water, "lily will never fall for that."

"We'll sadly Moony, we can't all be as close to lily as you. I wish!" James said, still laughing.

Sirius waved his wand and tried to dry off Remus.

"I wish I could be good at magic like you Sirius." Peter squeaked, but nobody heard him.

Once they were both dried, James snatched the potion and they ran back to the gryffindor tower.

Back in the common room, James told Peter to make conversation with Lily and slip the potion into her drink. About 10 minutes later, he came back sweating and shaking. "Did it." He whispered.

Remus Lupin woke up in the middle of the night. This wasn't uncommon as he often had nightmares. He had trouble getting his balance as he stood up. He hobbled into the bathroom. He blindly searched for his cup. Once he found it, he filled it with water and began sipping. He did this on a normal basis to calm down. He rubbed the wall searching for the light. It blinked on and his eyes slowly adjusted. But when Remus turned and looked into the mirror, Sirius's face was staring back at him. And when he screamed, all that came out was Sirius's voice.

Remus heard Peter's voice from the other room. "Sirius would you shut the hell up I'm trying to sleep?"

Remus clumsily ran into the bedroom. Sirius had quite long legs. He turned on the light and saw himself laying in bed. Remus ran over to his body and shook it awake.

Sirius woke with a start. "What?!WHAT THE HELL?!" When he opened his eyes, Sirius saw himself looking back at him. He jumped up and grabbed his wand. "WHO ARE YOU AND WHAT ARE YOU DOING IN MY BODY?!"

"Sirius! It's me, Remus! I swear its me!"

"Tell me something only Remus would know!"

"You slightly fancy James's mum but you'd never tell him!"

Then Peter jumped up as well. "YOU FANCY MY MUM?"

"For gods sake, somebody wake up Peter." Remus said in Sirius's voice.

After about 2 minutes of shaking, Peter (in James's body) finally woke up. The 4 marauders stood in a circle in the middle of their room.

"Alright." Remus began in Sirius's voice, "so were all mixed up. It had to have happened in Slughorn's office last night."

"So who's who?" Squeaked James. Peter obviously didn't like James's body.

"I think I got this..."Sirius said. "James and Peter swapped, and Remus and I swapped."

"We'll let's sort out one thing..." James said in peter's voice.

All 4 marauders were thinking the same thing and immediately looked into their pants. After a few "huh"'s and "hmm"'s, they all began to think about what could have caused this strange swap.

"I got it!" Remus said. "When Peter and I fell in that fountain!"

"So? It was just a fountain." James said. James was obviously trying to deepen Peter's squeaky voice.

"Yeah but remember? James you said you wished you could get along with Lily like me! And Peter said he wished he was good at magic like Sirius!"

"So it was a wish fountain? But wouldn't that make Peter and Sirius swap and you and I swap?" James questioned.

"I'm so confused." Peter and Sirius said at the same time.

"So to clarify," Remus began, "I am Remus, in Sirius's body. James is in peters body. Peter is in James's body. Sirius is in my body."

Just as Remus finished explaining, McGonagall angrily marched into their room.

"What is all this shouting?! It is 3 in the morning! What are you all doing out of bed?" She exclaimed. It was hard to take her seriously with curlers in her hair.

Peter began talking but Remus immediately covered his mouth.

"Um Remus had a nightmare and we're comforting him!" James fibbed quickly.

McGonagall's expression softened slightly. "Is this true ?" She asked nicely.

Sirius realized she was talking to him. "Um yes! Yes it is m'am. Terrible nightmare I had. I'm fine now though. Perfectly fine."

"Alright then. Go back to bed and make sure it doesn't happen again. 5 house points are to be deducted. Each!" McGonagall left, leaving the 4 friends staring at each other.

"You know what," Sirius said, "this might be pretty fun."
