In the Mushroom Kingdom, there is something special happening. It is the 22nd birthday of MK's ruler, Princess Peach. It is so special, that the ones planning the party, her 26-year-old boyfriend Mario, his twin brother Luigi, and Peach's guardian, Toadsworth wanted it to be a surprise.

Peach was working on what seemed to be endless amounts of paperwork when Toadsworth arrived at the scene.

"Hey Toadsworth. What's going on?" Peach asked.

"I see you have been working pretty hard."

"Yep. Just doing what every princess does. "

"Tell you what: Why don't you take a break from your work and come clear your head with a walk with me. Sound good?"

"Sure."

Peach got up from her desk and went on a walk with Toadsworth.

Back with the Mario Brothers, they were in the castle ballroom preparing the party decorations and all the planning for the party.

Mario was directing some Toads with the pink ribbons that were to dangle from wall-to-wall on the ceiling.

"Ok, a little bit to the left. More, more. Perfect!"

The light pink ribbons were perfectly placed and made the castle into a party room.

"Great job, guys!" Mario praised everyone in the ballroom and then turned to one of the chefs that were making the birthday cake, which about 9 feet tall, with white and pink trimmings and with 22 candles on the cake. It was so fragrant, you could smell the vanilla favoring from about 4 feet away.

"How's the cake doing, chef?"

"It's going really well, Mario. You did want vanilla, right?"

"Yeah. I told you that 3 times already."

"Sorry, I just get paranoid when I make cake as big as this for the princess."

"That's OK, it's still a good job on the cake though. I already can smell the vanilla."

"Whew! Thanks!"

Luigi walked up to his older brother after recently helping some Toads with the decorations.

"Wow, bro. Who knew that party planning could be so rough!" Luigi exclaimed.

"I couldn't agree with you more, bro."

Back with Bowser, he and a large group of some of his minions were already in the Mushroom Kingdom, preparing to attack the castle.

"Remember, on my signal, you guys will run in and invade this castle. You can have fun those stupid mushrooms, but the Mario Brothers are mine. Understand?!" Bowser ordered quietly.

"Sir, yes sir!" The minions addressed Bowser quietly to not attract attention to enemies ahead.

Bowser then promptly stomped up to the castle doors, scaring and capturing the mushroom guards that were near the door.

"It's payback time, Mario!"

Bowser then punched the door open and everyone, except Mario gasped in shock and fear.

Mario was the only one brave enough to stand up to Bowser, which was exactly what Bowser predicted.

"What are you doing in Peach's castle, Bowser?!" Mario shouted fiercely.

"Oh nothing much, just thought I'd stop by to pick up something, or should I say, someone." Bowser sneered.

"If you're here to kidnap Peach again, she's not here. Tough luck." Mario remarked as Bowser simply chuckled.

"Oh no, I'm not here for Peach."

"W-what do you want, then?!" Luigi finally spoke up.

"I'm looking at it!"

With that, Bowser used the Vibe Scepter to make everyone go insane with emotions. The Mario Bros both got affected by the "calm" vibe, which made them very sleepy.

"Koopa Pack, attack!"

A whole army of Hammer Bros came running toward the castle, swarming it.

Sadly, our beloved heroes and most of the toads in the castle were captured and tied up while the rest of the group were left crying, getting ticked off, or laughing like a hyena.

"You won't get away with this." Mario managed to snap weakly, as several Hammer Bros tied him up.

"Your senses must be pretty dim, because I already have." Bowser snarled as Mario finally dozed off into death-like sleep.

"Alright, men! Back to the castle!" Bowser yelled as he and all of his army went back to home base, taking the Mario Bros and some of their friends with them.

As for the party itself, it was ruined. Decorations were torn, presents were broken, and everything that the Mario Brothers worked so hard for was ruined. With the Mario Bros being held hostage, who can bring justice to the Mushroom Kingdom?
