Authors note: I do not own T.U.F.F. Puppy, Butch Hartman does, enjoy and review. :)

The rabbit finished his work and packed up "Another late night" he said with a sigh, the man's life was pretty boring and average, he closed his brief case and headed out of his office, he then left to the elevator and pushed the one button, the doors closed and it started moving "Hi there" he looked around the small space confused as he barely heard the whisper.

Soon the doors opened and he walked out "Over here" he heard the whisper again and looked around "Is someone there?" he shrugged and continued to his car "What are you waiting for?" he got outside and saw a figure smiling a sick grin "Care to play?" he stared at it for a moment "Who are you?" the figure stayed it the shadows as it moved away from him.

"Wait, where are you going?" the figure laughed a little "Want to see something fun?" chains rattled as it moved away, the rabbit's curiosity got the better of him so he followed after the shadow, the figure laughed again as he continued down the road "Wait!" after awhile he found himself at a school building "I remember this place, why are we here?" the figure stood itself on chains and grinned psychotically.

"Let's play!" the rabbit realized now that he was in danger "I should go" he tried to leave but a chain stabbed itself in front of him "HAHAHAAHAHAHAHAHA!" she laughed as the chains went around him and shot through the rabbit like tissue paper "I'll start my revenge with you, hahaha, and then the rest will follow" she laughed some more as the chains ripped the rabbit apart.

The next day at at T.U.F.F. HQ, the flea known as the Chief called in his top Agent "Agent Katswell, in my office immediately!" the tan cat looked confused "Oh boy, he sounds angry" her partner a white dog laughed "He always sounds like that, come on let's go" they got up from their desks and went to the Chief's office.

The Chief looked at the white dog annoyed "I asked for Katswell, not you Agent Puppy, wait outside" the dog looked disappointed "Aw man, okay" he left and the cat sat down "So what do you need Chief?" the old flea cleared his throat and put a folder in front of her.

"I have a new case for you and Agent Puppy" she opened the folder and quickly covered her mouth with her hand obviously sickened by the crime scene photos "Oh my god!" the crime scene photos were of some kind of animal torn limb from limb blood was everywhere, different parts of it's guts were hanging off of the front of a school and the eyes were missing, the creatures skin seemed to skinned off and the muscle tissue was obviously stabbed multiple times.

"His name was Mike Peterson, he went to that high school back in the day, recognize that school?" Kitty looked closer at the name of the school "Wait a minute...this is my old high school!" the Chief nodded "Bear's den High, your old school, even though this is the first actual murder, people have been disappearing for almost a month now" Kitty thought about the victim's name.

"Wait, Peterson? I remember that guy, he was a complete nerd back then" The Chief ignored her and continued "I want you and Dudley to go undercover and investigate the school, the kids there say it was a ghost, so I want you to blend in and learn more" Kitty looked at him confused "Why can't we just ask them?" the Chief laughed at her.

"Their teenagers Kitty" Kitty nodded "Good point" she got up and then left his office, Dudley ran up to her "So what kind of awesome mission are we on today!" she moved slightly to the right and he ran into the wall "OW!" Kitty sighed and helped him off the wall "Okay Dudley, we have to go to school" Dudley looked at her in horror.

"School!" Kitty nodded "Yes, we have to go undercover and investigate some recent disappearances and a murder, there are rumors of a ghost being the cause of it" Dudley instantly smiled "We get to fight against ghosts! Awesome!" Kitty rolled her eyes "I really doubt it's a real ghost Dudley, it's probably a student gone crazy and making it look like a haunting" Dudley just laughed.

"Yeah right, I bet there is a real ghost, and I'll prove it when we get there!" they soon went to Keswick's lab and he was already waiting for them "Ah, there y-you are, I've come up with some disguises and new names for you b-both" Dudley looked at him confused "Cool, what do you have?" Keswick smiled and pushed a button, and two big machines went over them.

The machines turned on and after a minute they went back up and Dudley was wearing pants, and Kitty was wearing a cheerleader outfit "Ahhh! pants!" Kitty smacked the back of his head "If you take those off, so help me!" then Keswick pointed over to the counter where there was two collars and a monitor.

They went over to the counter and the monitor turned on, and a blue furred cat appeared on screen "Hey guys, hey Dudley!" Dudley's tail started to wag "Hey Luna!" the cat ignored him and continued talking "sorry I'm not here right now, this is a recording, now if you'll look at these collars, they are the latest in disguise technology, wear these and you'll be in perfect disguise, it's not as good as the Chameleon's tech suit but it will do the job, go ahead and try them on!" Kitty and Dudley took the collars and looked closer at them.

Dudley put his black collar on and move a nod on it, then a white light went over him and when it was over a teenage Dudley stood there "Whoa! I'm a teenager again!" Kitty noticed he looked like a nerdy wimp "Yeah if that's a good thing?" she then put on the pink collar and the same light went around her, after the light disappeared she was a teenager again.

Dudley couldn't help but whistle at her "Wow Kitty, you look good!" Kitty rolled her eyes, she fit perfectly in the cheerleader outfit and she looked like one of the popular kids, then two backpacks came up from the counter and Dudley happily took one "Alright, secret agent backpacks!" Luna spoke again.

"If your wondering about the backpacks, they have everything you need to go back to school, and yes Dudley, I added a gadget system, they carry your tools and your books, good luck!" right before the monitor turned off a piece of paper came up, so Kitty put on her backpack and then took the paper, on the piece of paper was two names for them.

"Rosalyn Cruz and Dean Wright? I feel like I should know that Rosalyn name from somewhere?" Dudley shrugged "My undercover name is Dean Wright, right? Awesome!" Kitty and Dudley looked up and two tubes came down and sucked them up, soon they landed on the T.U.F.F. Mobile and Kitty drove off.

"Okay Dudley, we blend in as teenagers, and learn more about what's going on, then when we get the chance we investigate the crime scene" Dudley nodded "Got it, we first mingle with them, then we check the crime scene" Kitty nodded "Yeah, but remember I'm Rosalyn and your Dean okay?" Dudley thought about it for a minute.

"Um, is there like a name tag we can wear?"Kitty shook her head "No Dudley, just try and remember, okay?" he didn't know if he could, but he would try at least, after awhile they got to the high school and parked "Ah, Bear's den High...I'm not looking forward to this at all...my old high school days were not fun at all" Dudley jumped out of the car excited.

"I'm totally not going to be the wimpy nerd this time!" he ran inside and Kitty just calmly followed him, then a holographic image of the Chief came out of his watch "Alright Agents, I just got you both enrolled and I've uploaded your schedules in your personal Petpads" Kitty pulled out her Petpad and checked it "Oh, okay then, what's yours?" Dudley checked his own Petpad.

"Hey we have a few of the same classes" then the first bell rang and people came out of their classrooms "Hey look at the wimpy nerd HAHAHA!" some jocks said as they walked by "Oh come on, I haven't even been in my first class yet!" Dudley said frustrated, Kitty shrugged "Teenagers always do that, your automatically put in a group as soon as you walk in the door, like me" Dudley looked at her confused.

She smiled "Watch this *ahem* Hey girls! looking good, not as good as me though!" some other popular girls looked at her and smiled "Hey girl, keep it up!" Dudley's jaw dropped "You just insulted them, and they liked it!" Kitty nodded "Like I said, your put on a group the second you walk in those doors, look I got to go to my first class, after school meet me at the crime scene okay?" She said as she quickly left.

Dudley hung his head and went to class, they got through their first class just fine, but their second class they shared, their teacher looked at them as they walked in "Ms. Cruz, Mr. Wright, introduce yourselves and take your seats" Dudley walked up first and started sweating "He...hello, my name is...Dean Wright" before he could say anything else some Jocks laughed.

"Yeah..Wright!" they high five each other and laugh harder "What a nerd!" Dudley just hung his head and took his seat, the whole room laughed but they quickly stopped when Kitty walked up in front of the class chewing gum "What's it to ya!" she took her seat with just that and everyone stared at her "She...is..so cool!" the jocks said and everyone almost cheered but the teacher screamed at them.

"Alright, enough!" they all stop and he calms down "Now open your books to page one hundred and five" they all got their books out and opened them, after awhile they finally got out of the classroom "God, I hate school!" Kitty said as Dudley walked up to her "Hey Kitty, man today was long and boring huh?" she glared at him.

"I told you to call me Rosalyn" he smiled nervously as he remembered "Right, sorry, hey what's that?" he noticed a trophy and checked it out "Best violinist award...Kitty Katswell, you won an award!" she nodded "Yeah, I have a couple of those" some jocks and popular girls walked up to Kitty "Hey Rosalyn, want to hangout with us?" Kitty shrugged.

"Sure, I'll even let you girls walk on the ground I walk on...but not to close" Kitty walked off and the they followed after her "Dang she's awesome!" Dudley felt kinda lonely, but he knew she was in character so he couldn't be mad at her "I guess I'll do something else then" he walked to the crime scene and started looking around.

Shortly after he started Kitty walked in "God I thought I would never lose them" she noticed Dudley and went over to him "Dudley, I'm sorry about that scene earlier" he smiled "It's cool, let's get to work huh?" Kitty looked around "Wait a minute...the crime scene was outside...but we're inside" Dudley looked at her confused.
