I was playing wii sport't baseball at my local mall and I saw the catchers and notised that there was no legs on them. How that happened, but when they are batting their legs reappear.
That's simply part of the style of the Mii characters, I suppose.
Your appearance of your Miis body is differant in every game. In boxing their arms are gone but in wario ware they have the body of angels.
And when they're in the crowds in Wii Play table tennis, they only have bodies and heads, and they're bodies aren't the colours you set your Miis as.
Really?
