#but they're far too terrified by King Boo to refuse

[snazzy-suit]

What, or how, would King Boo react to Luigi getting kidnapped? Even if he doesn't care, would he try to find him? And what would the aftermath be like?

King Boo would be incredibly annoyed and extremely offended. Someone else managed to kidnap Luigi? This kidnapper better be some ancient eldritch god or he’s going to be pissed that some has-been succeeded where he failed.

[At the kidnapper’s hideout]

King Boo, dramatically busting through the warehouse doors: “Luigi, you incompetent oaf! I’m going to break every bone in your stupid body for making me miss my stories!”

Kidnapper 1: “Holy Jaydes! It’s King Boo! What are you doing here?! How did you even find us?!"

King Boo:

King Boo, to Luigi: “These are your kidnappers? How dare you let yourself be abducted by a gang of mortal half-wits!”

Luigi, tied to a chair: “Wha—I didn’t ask for this!"

Kidnapper 2: “Half-wits? We captured one of the Mario Brothers! The ransom we’ll get for him will set us up for life!”

King Boo: “And just who do you plan to collect the ransom from? His brother? Mario is a plumber, you idiots! He doesn’t exactly have a fortune laying around, and adventuring isn’t cheap!"

Kidnapper 1: “The princess will—”

King Boo: “Wrong! I’ll be picking up the tab, and only because you wrapped my nemesis up so nicely—like a gross, meaty present."

Kidnapper 2: “Uhh...okay...we want one—"

King Boo: “That’s too much. Here’s a corn chip I found—that's all he’s worth to me. I did tell you, Luigi, that I would one day sell you to a nightmare creature for a single corn chip."

Luigi: “Yeah, but you’re buying me with one, not selling—"

King Boo: “I believe that completes our transaction. Come along now, commode crony, we have a twelve-hour soap marathon to get back to."

Luigi, to the kidnappers: “DON’T LET HIM TAKE ME AWAY!"
