Mario Mysteries: Where did Mario go?

I am obviously not talking about Mario is Missing but about his absence in a Luigi game where it features Nabbit as a playable character. The game never explained it but have anyone made a theory of what happened to him?

I made a theory that it has something to do with King Boo.
Any good ideas for Yoshiking14x's first mystery?
 
I always thought that Mario was in Nabbit's bag the whole time.
 
Nah, Luigi didn't notice.

Nabbit's the one who murdered Mario. Along with Daisy, Waluigi, and Baby Luigi.
 
Mario took a vacation

Plot Twist II:

Mario got killed by Peta activists, as seen in one of their GREAT FLASH GAMES

Why did they leave Luigi alone then?
