At Koopa Kingdom Elementary, Bowser Jr. was organizing the colored pencils on his desk. Though he was having a hard time knowing which goes where. Having a hard time, he looked over to the student next to him.

Bowser Jr.: Excuse me, miss?

Student: I don't want to have to report you again.

Bowser Jr.: Haha! Oh yeah, you're the kid I pranked a while back. But no matter. I was just wondering, do you think the blue pencil should be the closest to me, or the red?

Student: I think they should all go stuck inside your-!

Bowser Jr.: Wait, I got it! I'll have the Yellow and Blue pencils closest. I prefer to keep the red and green far away, because they remind me of two people I hate.

Junior's teacher, Ms. Clawdice, walks into the classroom.

Ms. Clawdice: Good morning class. Sorry I'm late. I got caught in traffic on the way in here when that whole 'I'm-going-to-be-doing-this-for-the-rest-of-my-life' thing reared its ugly head and I…

Bowser Jr.: Blah, blah, blah! Can we get class started already?!

Ms. Clawdice gave Junior a glare before moving on.

Ms. Clawdice: Anyway, we have a new student starting today, so let's all put on a happy face for Fatz the Bully!

A person with green feet, no arms, a metallic blue body, no mouth, red eyes, and golden horns walked into the classroom. He looked a little too old to be in kindergarten, so he was likely held back. The entire class was wearing paper smiley faces.

Ms. Clawdice: Tell the class something about yourself, Fatz.

Fatz: Well, I like to kick people's butts.

Clawdice wasn't the slightest bit intrigued by it and just laughed.

Ms. Clawdice: What a card! Now Fatz, it's time to pick your seat. Just go ahead and sit anywhere you'd like.

The entire class except for Junior, dashed away. Junior took off his smiley face as Fatz sat next to him. Just then, he noticed Junior snickering and raised an eyebrow.

Fatz: What, may I ask, do you find amusing?

Bowser Jr.: *snickers* Your name is "Fatz"!

He laughs even harder just saying the name. That certainly made Fatz a little mad.

Fatz: And what would your name be, kid?

Bowser Jr.: Junior. Bowser Jr. You know, heir to the Koopa throne. Soon to be ruler of this kingdom, the Mushroom Kingdom, then the world. You get the gist. Nice to have another loser in this classroom I can poke fun at.

Fatz: Hello, Junior. I'm gonna kick your butt.

Junior gasps, but then laughs again.

Bowser Jr.: Very funny, pal! Very funny! But no one in this classroom has the guts to stand up to me. You're just trying to make yourself look cool.

Fatz then leans over Junior, menacingly.

Fatz: No… I mean it.

Junior still wasn't giving in, and laughed.

Bowser Jr.: Hehe! That time it almost seemed like…

Fatz stares deeply into Junior's soul with his eyes saying without a need for words "I MEAN IT!". His stare could easily rival a certain green guy. Junior himself was horror-struck.

Bowser Jr.: ...you did mean it.

He raises his hand.

Bowser Jr.: Um… Ms. Clawdice?

Ms. Clawdice: Yes, Junior?

Bowser Jr.: Can I be excused for the rest of my life?

She chuckles a little.

Ms Clawdice: Why no, Junior. I'm in the middle of a spelling tutorial right now. You can't afford to miss this information.

Bowser Jr.: Yes… sorry…

Fatz looked over to Junior, and would've grinned if it weren't for the lack of a mouth.

Ms Clawdice: Now, can I please have a volunteer to come up to the board? How about you, Fatz?

Fatz came to the chalkboard.

Ms. Clawdice: Please spell the word "death".

Fatz started drawing, despite the lack of hands.

Ms. Clawdice: Please turn and show the class what you drew, honey.

Fatz steps out of the way and shows that he drew pictures of him kicking Bowser Jr.'s butt. Junior screams seeing this.

Ms. Clawdice: My, how very creative! We have an artist in the class.

Everyone applauds except for Junior, who ran out of the class in fear, and into the boys bathroom. He hid inside a toilet.

Bowser Jr: I just don't understand. Why would Fatz want to kick my butt? What did I ever do to him?

*flashback*

Bowser Jr.: Nice to have another loser in this classroom I can poke fun at.

*end of flashback*

Bowser Jr.: Aw crud!

He heard the door open and footsteps approaching.

Bowser Jr.: What was that?! Someone's coming! They're getting closer! I've just got to act natural.

A kid opens the toilet's lid and saw a Koopa Shell in it.

Kid: *sardonically* Oh, that's real nice.

He walks away and Junior comes out.

Bowser Jr.: Phew, I thought for sure that was gonna be…

Fatz opens the stall.

Bowser Jr. FATZ! Uh, hello, sir. Kick any good butts lately? Yeah, I remember last week, I was kicking this guy's butt real good. And he leans over and says, 'Hey, you know, life's like a bucket of wood shavings.

Fatz looks dumbfounded.

Bowser Jr.: Except for when the shavings are in a pail, then it's like a pail of wood shavings! Hehe!

Fatz: Hey, that story really speaks to me.

Bowser Jr.: Really? What's it say?

Fatz: It says now, I'm gonna kick your butt twice as hard.

He leaves. Junior flushes himself down the toilet, clogging it.

Later, Junior was walking down the hallway with a clipboard.

Bowser Jr. …and I leave my clown car to Lemmy, and my Magic Paintbrush to… oh God, I just can't do this!

A phone next to him started ringing and he answered it.

Bowser Jr.: Death row, next in line speaking.

Roy: Hi, I'd like to place an order for delivery.

Bowser Jr.: Roy? Is that you?

Back in Bowser's Castle, Roy has dialed the wrong number for Mario Bros. pizza.

Roy: Yeah, hey Mario. Let me get a large double olive, double-

Bowser: Roy, listen! It's me, Junior! I need your help!

Roy: You're working at Mario bros. pizza now?

Bowser Jr.: What? No, listen! I'm in big trouble. There's a new guy at school here and he wants to kick my butt! Listen, you're big and strong, do you think you could come down here and maybe rough him a bit? Just to get him off my back? Please, Roy, I'm so scared, it feels like I'm gonna throw up.

Roy: No, they're not closed. I know, you want olives.

Bowser Jr.: Huh?

Roy: Oh, I'm sorry, Junior. I was just talking to my old high school buddy, Fatz.

Bowser Jr. was horror struck. Back at the castle, Fatz was sitting at a couch enjoying a beverage.

I bumped into him at the soda store, isn't that funny? He said he got held back to kindergarten after relentless bullying to other students. Hey, funny. That's the grade you're in right now, so you might've met him. Well, let me get going. He's got to go back to school soon. He says he's got to kick somebody's butt.

Junior was even more horrified, knowing that his closest sibling was friends with his school bully. He runs away screaming, not even bothering to hang up the phone.

Roy: Hello? Is this Mario bros. pizza?

At the end of the day, Bowser comes to pick his son up?

Bowser: Hey, Junior. How was school today?

Bowser Jr.: Papa, can I not go to school ever again?

Bowser: What? But why? Something bothering you?

Bowser Jr.: Well, there's this new school bully named Fatz, and he says he's going to kick my butt!

Bowser: What?! There shall be no butt-kicking to any son of mine! Junior, leave this to me.

Bowser Jr.: Oh, thank you thank you thank you Papa! I knew I could count on you.

Later on… Junior was eating dinner and his father came up to him.

Bowser: Well son, good news! I talked to Fatz for you. I used your name. It was all a misunderstanding.

Bowser Jr.: YOU WHAT?!

Bowser: He was never going to kick your butt at all! You see Junior, Fatz is from a town where kicking someone's butt means that he wants to be your friend

Junior looks out the window and sees Fatz beating up a punching bag with his face on it.

Bowser: And maybe play some sports with you on weekends.

Bowser Jr.: I've got diarrhea!

He runs out and sees an older bully with a mustache in his car.

Bowser Jr.: Huh? Are you Fatz's dad?

Fatz's Dad: Why, yes I am.

Bowser Jr.: Okay, see, I didn't know where else to turn! Roy couldn't help me, and my dad only made it worse. I sit next to your son Fatz in school, and he is a fine boy and all, and I don't want you to take this the wrong way, but he wants to kick my butt.

Little did he know, Fatz heard the whole thing.

Fatz: Dad, what're you doing?

Fatz's Dad: Uh, nothing son.

Fatz's Dad was sweating as he was actually afraid of his own son.

Fatz: What did I tell you about talking to strangers?

Fatz's Dad: *whispering to Junior* Now he's gonna kick my butt!

Junior runs away screaming. He runs so fast that he ends up in the Mushroom Kingdom. The Toads look confused.

Bowser Jr.: Out of my way! Out of my way! Can't you see he's gonna kick my butt?!

The Toads look in the direction Junior's pointing to see Toadsworth at the bus stop.

Toadsworth: Hi there young people, nice day today.

Toad: So, you like kicking butts, do ya? Well we'll show you, old man!

The Toads start beating up Toadsworth while Junior hides in a garbage can.

Bowser Jr.: Okay, okay, I got to skip town, start a new life, live under an assumed name! "Rowseb RunioJ". Yeah, that's good. Grow a beard, and then shave it off, and live happily ever after.

Fatz is behind him driving a garbage truck.

Fatz: Yeah, except you forgot the part where I kick your butt!

Junior gasps three times, and runs for his life while still in the garbage can. The garbage truck came at him full speed. This reminded him of a videogame he played where a blue hedgehog was running through the city, and had to outrun a military truck. The truck was getting closer and Fatz began to laugh evilly. Just then, Junior ran through an item box from Mario Kart, and got a banana. He dropped it behind him. Fatz saw the banana and screamed. The truck slipped over the banana and crashed.

Fatz woke up to see Junior with a bouquet of roses.

Bowser Jr.: Hey, Fatz, you feeling better? Sorry that I made fun of you back in school.

Fatz: *cough* What? Where am I?

Dr. Mario: Why, you're in the hospital. This young boy saved your life. He performed CPR for five hours straight.

Bowser Jr.: Yeah. They said you'd be okay after the first few minutes, but I just wanted to be sure.

Fatz: Wow, I'm touched. I'll have to remember that when I'm kicking your butt.

Junior gasps.

Fatz: Those flowers for me?

Junior ran out of the hospital screaming again.

Bowser Jr.: He's still gonna kick my butt!

The Toads look to Toadsworth again.

Toad: How many times do we have to teach you this lesson, old man!?

They run up to Toadsworth.

Toadsworth: I love the young people!

Junior runs back to Bowser's Castle in fright.

Bowser Jr.: I'm too young to have my butt kicked! There are so many things in life I haven't gotten to do!

He thinks about taking over the Mushroom Kingdom, and having everyone bow down to him. A knock is heard on the door.

Bowser Jr.: Who is it?

Fatz knocks down the door with a menacing glare on Junior.

Bowser Jr.: Fatz!

Fatz: It's butt-kicking time!

Fatz preps himself up for butt/kicking as Junior hyperventilates.

Fatz: Let's do it!

Bowser Jr.: Oh no…

Fatz: Are you ready?

Bowser Jr.: Hold on.

He puts his bib over his eyes, not wanting to see himself get beaten up.

Bowser Jr.: Okay, I'm ready.

Fatz charges over to Junior, but it doesn't hurt him. It just bounces off.

Bowser Jr.: I said I'm ready.

Fatz: Huh?

He tries to hit him again, only to get the same result. Jr. takes off his bib.

Bowser Jr.: Didn't you hear me? I said I'm ready.

Fatz hits him again.

Bowser Jr.: Really? You call that butt-kicking? That was pathetic!

Fatz gets angrier and keeps trying to punch him, but never inflicts damage on him. Junior yawns in boredom and walks off, continuing his entire day while Fatz keeps trying to kick his butt.

The next day, Bowser Jr tries to take over the Mushroom Kingdom, gets beaten by Mario, plays cards with the Koopalings, walks out of the bathroom, sleeps in bed, eats breakfast, and goes to school. All while Fatz keeps trying to beat him up to no avail.

At school, Fatz gets tired still trying to beat up Junior and collapses to the floor. The entire class cheers for him, but Junior couldn't help but feel a little bad for Fatz.

Bowser Jr.: Do not cheer for me, my fellow classmates. Fatz was the real victim here. A victim of a society that's riding down a violent road to nowhere; a road I call…

Junior raises up his fist and clenches it.

Bowser Jr.: ...'violence road'.

Ms. Clawdice walks in the classroom.

Ms. Clawdice: Sorry I'm late, class, I…

She gasps as she sees Junior's fist in the air and Fatz on the ground, making it look like Junior beat up Fatz.

Ms. Clawdice: Junior! I can't believe you beat up a new student! I'M GOING TO KICK YOUR BUTT!
