It was a rather cloudy day in Dark Land (cloudy?) and the Koopalings were all playing Super Smash Bros. Brawl in the lounge.

Larry: Come on, jump! JUMP!

Roy: Punch! Haha... No, NO! Aw, I got killed by Pikachu!

Morton: Who's Meta Knight?

Iggy: Me.

Morton: Then YOU DIE!

The Koopalings were all having a blast. Until Bowser came in the lounge smiling in an evil kind of way.

Bowser: Kids.

The Koopalings continued to play.

Bowser: Kids.

The Koopalings continued to play.

Bowser: Kids!

Must I say it?

Bowser yanked the cords out of the wall.

Koopalings: HEY!

Bowser: Everyone listening NOW?

Morton: Against our wills...

Bowser: What was that, Morton?

Morton: Nothing.

Bowser: ... Anyways, I came to tell you all I'm going on a major bank robbery tomorrow.

At this the eight kids went wild.

Koopalings: We're going on a robbery!

Bowser: I said I was going on a bank robbery.

At these words the Koopalings stopped singing and all their faces took on astonished and angered expressions.

Morton: That's not fair!

Wendy: Daddy, I want to go!

Bowser Jr: Me too!

Bowser: Wait, you didn't let me finish. I'm going on a bank robbery and I'm taking two of you with me.

Wendy: Who's going?

Iggy: And why only two Koopalings?

Bowser: I need a small group because the security is heavy and I'd need to make a fast get away.

Iggy: ... Ohhh...

Bowser: And there is going to be a contest to see who is going with me.

Bowser Jr: Aw... Unless it's a drawing contest I'll lose for sure!

Roy: Can we turn Super Smash Bros. Brawl back on?

Bowser: That’s what the contest is going to be! And no.

Roy: Awww...

Bowser: It's going to be a fighting contest. In one hour you will all be having an all-out melee! The winners of the contest, as in the last two standing, will come rob the bank with me tomorrow.

Iggy: Can we bring weapons?

Bowser: Yes.

Lemmy: Is a ball-

Roy: Or pair of shades.

Lemmy: -considered a weapon?

Bowser: The ball is but not glasses. Now prepare yourselves, because the fight is in one hour.

Bowser left.

Roy: ... The best experience we can get is virtual experience, right?

The Koopalings then continued to play SSBB.

*****One Hour Later*****

The Koopalings had all showed up except two. Each had a weapon.

One had a weapon that the Koopa had built and that was also a weapon in Super Smash Bros. Melee. One had a weapon that she had used in Super Mario Bros. 3. One had a large war hammer the color of its shell. One had a large circus ball. One had a paintbrush. Another had an enemy commonly found in Grass Land or Pipe Land strapped to its back.

Bowser: Okay... Everyone's here except for two of my kids...

The Koopas who hadn't shown up were in the bathroom talking.

???: I think we should team up.

???2: Me too.

???: Good. Say? Where's your weapon?

???2: ... I don't have one.

???: You can borrow one of my weapons.

The first Koopa handed his brother a tennis racket, the same as his. The two Koopas then scurried outside.

Bowser: Good. Now everyone's here. LET THE FIGHT BEGIN!!!

A bell rung. And the Koopas began to fight.

The two Koopas who teamed up cornered a brother who had a silver war hammer and managed to take them out by slamming their weapons into their brother's face.

Then a Koopaling threw a large circus ball at a younger sibling. But since it was a circus ball it didn't hurt at all. The sibling then drew a picture of a Muncher, and the Muncher ate the ball. Enraged, the weaponless Koopaling charged at the Muncher but was defeated.

Meanwhile another pair of Koopas were fighting. "You wouldn't hit a guy with glasses!" one Koopa taunted. The other Koopa threw a punch and missed. "You COULDN'T hit a guy with glasses!" the first taunted again. The Koopa jumped high in the air and kicked his sibling's face, KO'ing her.

Meanwhile the one who hadn't got in a fight with a sibling was ganged up on by the two truced blue heads. Despite being outnumbered, the Koopaling used fire to KO the Koopa that was younger than him, and destroyed the other Koopa's weapon.

The weaponless Koopa took a silver war hammer it found on the ground and KO'd the youngest Koopaling with it. Then a Koopaling fired thick, green beams of light at a brother and killed its weapon. Then the Koopaling with a blunt weapon knocked out his brother who had a weapon.

Bowser: Stop! You two! Good job! You both will come with me to rob the bank.
