You would see Mario running around in the Mushroom Kingdom, Picking up Coins, beating up some baddies, and not to mention, Being a cheerful guy.

Oh, Hello! He would run up to you.

It's-a me, Mario! He would say in a happy tone.

I hope you have-a good time here at the Mushroom Kingdom, Woohoo! He would smile while flashing a thumbs up at you.

Well...if you need-a me for your plumbin' needs, you know who to call! Wahoo! He would say while running from you.

He's a nice plumber!
