'In New Super Mario Bros. DS and New Super Mario Bros. 2; how come we can use (Luigi) you by holding L, R and A?'

From-@Creeper_Chan

Luigi: Nice one, buddy! ^w^ During production; they almost left me out of the game completely! Only Mario could- yet again as usual; go on another adventure with out me. I bawled my eyes out when they let me test the Beta version of New Super Mario Bros. DS while it was in testing.

(Ruījī: pronounced: Ru-Weegie
Flashback:
Luigi: Why no Weegie? ;-;

Shigeru: Ruījī-san! There's no need! As you can obviously see in the intro, Peach and Mario are walking together! That's romance! We didn't need you in it!

Luigi: I know! But still!

Shigeru: But still- what? Ruījī!
You're not Peach's boy, are you!

Luigi: *Insert wailing clips*

Shigeru: *Feeling sorry* Uh. I'm sorry ;-;

Luigi: Y-you are?

Shigeru: How dare me neglect one of my creations? :D We originally made you to be our player 2. But Ruījī.. how about we give you a fancy code?

Luigi: Huh?

Shigeru: So players can use you.. We'll give them a guide to the code- once they beat the game as your dare devil brother- Mario-san! ^^

Luigi: Yay! *Hugs Miyamoto*

~Players must hold L, R and then A to play as Luigi~
