I can’t fully understand what Mario actually means when he throws Bowser in to the mine.
It sounds a little blurry, so I hoped someone could translate that for me.
Answer
He’s saying “So long(-a), Bowser“.
You can hear the audio clip without the background music on The Mushroom Kingdom. Basically, it is just saying “So long, Bowser” with a Mario affectation.
