Here is a random Mario question.

[Shyghoul]

DUDE.
THAT'S THE ANSWER.
MARIO SAID SO IN THE MARIO SPORTS MIX INTERVIEW

The answer is still money.

 

[Iggy Koopa Jr]

Yeah. He does not care about the princess. Just about his life and the amount of money he has. And hitting blocks.

 

[Ray Trace]

He's a fictional character consisted of a bunch of ones and zeros. My bet goes to he doesn't have an idea of perfect happiness.

Just because he's a fictional character doesn't mean he can't have an idea of perfect happiness. It's just that Mario is an overly bland character with no developed personality and stuff.

Besides, he explicity said this is his idea of perfect idea of happiness:

No. The answer is seeing this shiny question block. And then he punches it. And a beautiful 1-up mushroom comes out! And another! And another! And another! AND ANOTHER! He could save the princess forever!
As said in the Mario Sports Mix interview with Mario.
