It is peaceful in the Mushroom World. Ludwig is sitting in his castle, crying softly. Then, Mario busts down the door.

Mario: Okay Ludwig. Time for our weekly fight.

He notices Ludwig crying.

Mario: Huh? Why are you crying?

Ludwig: B-Because... MY CHOCALATE WAS STOLEN BY JR. TROOPA! WAAAAAAAAAAAAAAAAAAAAAH!!!

Mario looks at him blankly before laughing his guts out.

Mario: JR. TROOPA?! HAHAHA! Very nice joke!

Ludwig: Unfortunately, I'm serious.

Mario stops laughing. But in his mind, he is rolling on the floor, laughing.

Mario: Oookay... Tell me what happened.

Ludwig: Okay. But promise not to laugh.

Flashback...

Jr. Troopa: Hey Ludwig, can I steal all your chocolate?

Ludwig: Sure, whatever.

End Flashback...

Mario: I think I understand.

Despite what he said, in his mind, he is literally laughing his guts out.

Ludwig: So... what do I do?

Mario: Do what I do! Go on an adventure of epicness!

Ludwig: Yeah.... And that will increase my street cred! Bye!

Ludwig runs out of his castle. Then, Mario begins laughing like a maniac.

Ludwig: Epic adventure, here I come!

So, Ludwig goes through Grass Land...

Piranha Plant: (tossing shells) at Ludwig How does this feel, little man?

Ludwig: Ow! Ow! Ow!

He goes through Desert Land...

Ludwig: (sinking in quicksand) Help m-

He sinks.

Buzzy Beatle: Wow. He even makes Mario's job look easy.

He goes to Water Land....

Ludwig: MWHAHAHAHA! With this flying machine, I can beat this place no problem!

Paratroopa: You cheat!

He cheats through Giant Land...

Gargantulan Goomba: You still cheat!

Ludwig: Like I care!

He crashes in Sky Land...

Ludwig: Erg... What hit me?

Chain Chomp: Look! It's the cheater!

Group of Monsters: Get him!

Ludwig: Eep!

He limps through Ice Land...

Ludwig: So... cold... Help...

Buster Beetle: ... Nah.

Goomba: Hey. I heard that the world championships of Bomb-Ball is on.

Buster Beetle: Sweet! Let's go!

He meets his old subjects in Pipe Land...

Ludwig: Hello, old subjects! I'm on a quest to retrieve my chocolate from Jr. Troopa!

Koopa: ... COUGHloserCOUGH!

Finally he gets to Jr. Troopa's home in the Bowser Badlands.

Ludwig: Open up, Jr. Troopa! I demand my chocolate back!

Jr. Troopa opens the door, holding a wheelbarrow filled with chocolate.

Jr. Troopa: You know, you could have just called instead of coming here. I could've had a Lakitu deliver it.

Ludwig: …

He faints.
