Has this happened to anyone else before? Was this because of the spinout? Or just an extremely lucky angle? Could this be replicated? Especially on other tracks? So many questions.

I know in Bowser's Castle at the small bridge with lava inside the castle, if you fall at just the right angle (fall between the wall and the lava) you clip through the wall, go through the lava and go below the stage, It doesn't really help in any way it just wastes more time. But on Koopa Troopa Beach that hasn't happened to me, but it does happen on other stages,
