Quick A/N, Sorry if this wasn't clear, but Lily is the one in Ravenclaw. I thought it's cool if she is because she's always struck me as the type of person who kind of likes being in the shadows and being the brains behind the operation and not necessarily getting the most credit. Lily is very courageous, but she has the demeanor of a mix of Griffindor and Ravenclaw, but she was put in Ravenclaw. Rose is in Griffindor because she is loud and proud. Oh, I'm putting up chapters pretty quickly because I'm really having fun with this, and the reviews are really helping and giving me ideas.

Oh yeah, any suggestions for plots are welcome.

Chapter 5, The Prank Mistake

Part 1, The Wrong Girl

"Ok troops!" James commanded the surrounding boys, "We need damn good prank and we need it now!"

"James, we're right here, you don't have to yell, you'll wake up the whole house," Sirius informed him.

"I don't think this is such a good idea James," Remus commented, "even if Rose claims to hate Petunia, sisters are very close, they fight like cats and dogs, but don't come between them."

"You are very wrong, Mooney, don't you listen when Rose talks about Petunia? She hates her. Didn't she even once say that she wold love to make Petunia get what's coming to her?" Peter said in one of the moments when he spoke.

"Peter's right," James announced.

"I am?" Peter asked, surprised.

"Yes you are, and I have an idea."

The four boys slipped into the Ravenclaw house under the dark of night, underneath the invisibility cloak, with the password 'fairy dust,' they learned from standing around the corner and listening to those who entered.

"What year is she in?" Peter asked. Sirius slapped him on the back of his head.

"You dolt! Petunia and Rose are twins," Sirius whispered.

"Keep it down!" James hissed at them. "Let's move, move, move. Operation Petunia is under way."

"You make up really bad operation names, I hope know that," Sirius commented.

"And you think you could do better?"

"Now is not the time," Remus said, stopping the up coming argument. The four made their way up the right staircase to the fifth floor. They quickly got to work. They decided to use muggle products so they wouldn't have to use any complicated Charms, which none of them were good at. The boys had decided to go one step farther than just getting Petunia, they had decided to get that girl she had been talking to on the train, but they couldn't decide which one she was, so they prank every girl in the room.

When James had seen Rose's sister, his breath was taken away, she looked so beautiful, then he reminded himself that she was probably the type of girl who made sure she looked the best at every possible moment and Rose had said this girls was a maniac.

"Ok men, we're out. Job well done, let's go get some sleep," James commanded the 'Troops' as they sprinted along the corridors back to Griffindor Tower. 'Won't Rose be surprised,' James thought to himself as he fell asleep.

Part 2, Honey, That's How It Goes

Lily woke up feeling sticky and grimy. She wasn't the type of girl who cared extraordinarily about her looks, but she did enjoy being clean. Lily sat up. The whole room was covered in string, it was everywhere. Lily opened her mouth to wake up the others and something wet began to pour on her head. It was honey. Sweet, syrupy, honey. Lily was about to scream when something else fell on her, feathers, lots and lots of feathers. Lily looked up to make sure nothing else as going to fall on her as she was about to speak. When she decided it was safe, she opened her mouth again.

"Tapa," she whispered through the still air, "Tapa," Tapa woke up with a moan.

"Why is your skin green?" Tapa asked looking through her half-closed eyes.

"It is?" Lily asked, looking down at her hands. "Oh bloody 'ell. Should we wake the others up?"

"Sure, but can you tell me why you look like a chicken who's feathers have been pulled off and has green skin?" Tapa said.

"What's going on?" a voice asked from the other side of the room. It was the Rachel Parson, AKA the ditz of Ravenclaw.

"Don't know, when we figure it out we'll tell you," Lily informed her. Rachel woke up the other three girls in the dorm who all screamed when they saw what was going on. Rachel insisted on the first shower and came out smelling like a dungbomb. Another girl, Gena, walked past Lily's bed and got hit with a pie in the face that was obviously intended for Lily. Tapa and Lily started laughing hysterically while another round of screaming proceeded.

All six girls managed to get downstairs before the end of breakfast. They had all managed to get cleaned off except Rachel smelled slightly like dung and Lily had purple hair and green skin. All of them looked murderously for the person who had done this.

Part 3, Oops

Rose came into the Great Hall and saw an amusing sight. A girl had purple hair and green skin. Rose then realized this girl was her sister. James, Sirius, Remus and Peter were laughing hysterically.

"You like?" James finally got out.

"What did you do to Lily?" Rose said in a calm dangerous voice. The Marauders stopped laughing and looked at each other.

"I thought your sister as Petunia and you hated her. Who is Lily?" Sirius asked.

"My other sister!" Rose yelled. Rose walked toward lily and out of earshot of the Marauders.

"She has another sister?" James asked. "Never knew there was a Lily Evans in this school."

"Yes you do James, she's the one person you complain bout the most. Isn't it because her name is usually on top of yours on grades? She always gets first and you get second. Did you say last year that if you were ever to meet Lily you would give her a piece of your mind?" Peter prompted.

"Not the time Peter," Remus informed him. An angry Rose came over with an angrier Lily.

"What do you boys have to say for yourselves?" Rose asked sternly.

"Oops," Sirius let out. Both girls were extremely short and standing up he would have towered over them, but they looked very scary at the moment.

"Uh, sorry," James said nervously. "We thought you were the Petunia Rose was always complaining about."

"If I was Rose I would take that as an insult. But I'm not, but I think you deserve punishment. Oh Tapa!" Lily called. The girl who they had seen with Lily came over. She looked angry also.

"Be glad she's not calling over Rachel or the others," Tapa told them in an evil voice. The Marauders looked very scared. "My dear friend, what did you have in mind?" Tapa's voice had changed completely to a sweet an angelic voice.

"My dearest sister," lily said gesturing to Rose.

"What, you think Petunia is dearer than I am?" Rose asked jokingly.

"Of course not, but I have a plan." The Marauders looked terrified. The three girls huddled together. "On the count of three. One, Two, three." Their wands blazed. There was a horrible blue light. James thought it was all over for him and it was, it truly was.

Their hands began changing and so did their hair.

"What happened?" James asked. He grasped at his throat. What had happened to his voice? He then realized his hands couldn't grasp his neck, or anything else for that matter. His fingers were sausages, jut like a little kid's drawing of a hand. He was now wearing a baseball cap and had pointy, furry ears on the top of his head.

James heard music in the background and before he knew it, he, Sirius, Remus and Peter were singing.

Hey, do it now
yeah hey

hey
Once there was a boogie singer
Playin' in a rock & Roll Band
And never had no problems
Burnin' down the one night stands
Well everything around me, yeah
Got to stop to feelin' so low
And I decided quickly, yes I did
To disco down and check out the show

Yeah they were
Dancin' and singin'
And movin' to the groovin'
And just when it hit me
Somebody turned around and shouted

Play that funky music chipmunk
Play that funky music right
Play that funky music chipmunk
Lay down that boogie and play that funky music till you die
Till you die? Yeah, uh huh

I tried to understand this
I thought that they were out of their minds
How could I be so foolish, how could I
To not see I was the one behind
So still I kept on fighting
Losing every step of the way
I said I must go back there, gotta go back
And check to see if things still the same

Yeah they were dancin', and singin'
And movin' to the groovin'
And just when, it hit me
Somebody turned around and shouted

Play that funky music chipmunk
Play that funky music right
Play that funky music chipmunk
Lay down the boogie and play that funky music til you die
till ya die? yeah, oh till ya die

Gonna play that electrified funky music now

Spoken:
Hey wait a minute
Now first it wasn't easy
Changin' Rock & Roll and minds
And things were getting shaky
I thought I'd have to leave it behind
oh but now its so much better
it's so much better
I'm funking out in every way
But I'll never lose that feelin'
ya know I won't
Of how I learned my lesson that day

When they were
Dancin' and singin'
and movin' to the groovin'
And just when it hit me
Somebody turned around and shouted

Play that funky music chipmunk
Play that funky music right
Play that funky music chipmunk
Lay down that boogie and play that funky music till you die
Till you die,
oh till you die

They shouted play that funky music
Play that funky music
Play that funky music
Gotta keep on playin'
funky music
Play that funky music

"I loved Alvin and the Chipmunks as a kid," Rose said evilly, "didn't you?"
