There`s this thing i noticed, and excuse me if i sound like captain obvious, but look at the mario special moves section, when he is doing the mario tornado you cant see the FLUDD, wich is odd cause the flood has two stances so far, standby wich is when is looking up and should be viewable, or attacking when it goes to the front... in wich case it should be viewable as well.
If you think about it, mario`s tornado is not really stated to be a down smash *wonders*
