Once upon a time, Bowser is getting sick of always failing to capture Princess Peach, getting defeated by Mario, and not taking over the world.

Bowser: So sick... Need medication!

NO! NOT THAT KIND OF SICK!

Bowser: Oh...

So, he decides...

Bowser: I'LL JUST TAKEOVER SOMEWHERE ELSE! But not just anywhere else... I'LL TAKEOVER A PLACE THAT WON'T REALLY CONSIDER ME A THREAT BECAUSE I NEVER TRIED TO TAKE IT OVER!

So, he puts the names of places he'd know how to defeat very easily on a dartboard. He throws a dart, and it hits Beanbean Kingdom.

Bowser: EXCELLENT! KOOPALINGS!

The Koopalings are there immediately, hoping that their dad had discovered what Roy and Ludwig did...

Bowser: WE'RE TAKING OVER THE BEANBEAN KINGDOM!

Koopalings: *groan*

Bowser: But I thought you guys liked being in games!

Wendy: But we were actually already IN that one!

Bowser: Oh yeah...

Roy: Well, what do we get out of it?

Bowser: I'll buy you all food seats for Roy's Sports Hall. Not only that, I'll order you all your favorite meals.

Koopalings: YAY!

Roy: Why don't I just usually get a food seat?

Bowser: You can't afford your own prices. Anyway, TO THE BEANBEAN KINGDOM!

Koopalings: YAY!

The Koopalings are flying in their doomships. Bowser is turboing ahead in his Clown Copter. However, he crashes in Stardust Fields.

Iggy: Should we save him?

Ludwig: Take over the kingdom first, rescue Dad second.

Lemmy: YAY!

After a long day of taking over the Beanbean Kingdom, the Koopalings go to Stardust Fields.

Larry: Where is King Dad?

???: Right here!

The Koopalings look at Tolstar, who has Bowser in a cannon... again!

Tolstar: And unless you pay me 100 coins, your dad takes a trip to the other side of Plit!

Lemmy: Didn't the Mario Bros. defeat you in Superstar Saga?

Tolstar: Well, I revived myself,

Morton: Oh!

Roy: Here you go!

Tolstar: These are Dark Land coins! I only accept Beanbean!

Wendy: Well, goodbye Dad!

Bowser: WAIT! Kids, come back!

The Koopalings come back to Bowser.

Bowser: Now, whoever pays the nice monster first gets a food room in Roy's Sports hall for a year and 10,000 Dark Land coins!

Koopalings: YAY!

So the Koopalings set off to get money to pay Tolstar. One Koopaling tries to make a money machine, but is arrested by Beanbean police for illegally making money. One goes to Beanbean Castle Town and steals 1,000 coins from Queen Bean. However, he also steals the Beanstar, which goes out of control and breaks his very fragile glasses. The person who might've gotten in trouble with Bowser that day is standing outside the Beanbean Castle window, and all of the money falls on his lap.

While he is running to Bowser, the third Koopaling you had to fight in Superstar Saga throws his favorite object at him, knocking him out, and steals half of his money. He tries to hustle to Bowser, but a bald Koopaling stands in the way and takes half of his money. He wants more, so he decides to rob Woohoo Hooniversity, but gets defeated by the 3rd Koopaling you had to fight in Super Mario Brothers 3. It takes 150 coins from him. It goes toward Joke's End to rob all of those at the tea party, but gets taken out by a Koopaling that was ready to blackmail all day.

This Koopaling takes half of the money, and gets back to Tolstar. However, he doesn't have enough, and Tolstar calls the cops on him for no real reason, but he gets sent to jail anyway. The other Koopaling in jail made an invention that let him run his molecules through the wall. He takes 50 coins from the Koopaling at Woohoo Hooniversity. Then, he goes to Beanbean Castle Town and steals 450 coins from the one who still had money. The one he robbed, however, beats him up and takes all of the money. He goes to Little Fungi Town for some relaxation, but gets hit by a blinded Koopaling. He takes half of his money, and goes on the path to Tolstar. However, he is robbed by a mysterious figure and a Birdo. They split the scene with 200 coins. One Koopaling is lucky enough to get out of jail with his money still intact. He sees his brother that just got robbed and Ko'ed, and steals the rest of his money.

On his way to Tolstar, he sees Kamek all beat up for failing a hypnotism. He pities him, and gives him all of his leftover coins. The Koopaling approaches Tolstar and gives him the money. Tolstar thanks him, and tries to shoot Bowser out of his cannon. However, it backfires, blows up, and sends the Koopaling and Bowser to Koopa Kastle.

After much work, Bowser got all of his kids back.

Bowser: First of all, Kamek, how much money did my generous child give you?

Kamek: I forgot.

Bowser: Oh well... Anyway, the person who saved me was...
