Make all those options in the poll using taunts!
UpTaunt: Big
DownTaunt: Mini
SideTaunt:Small
For original size...hmmm while in UpTaunt press A+B?
Couldn't he just make it so that you have to press the taunt button again to return to normal size?
Up Taunt -> Big -> Up taunt again -> Normal Size
Side Taunt -> Small -> Side taunt again -> Normal size
Down Taunt -> Mini -> Down taunt again -> Normal size
if he can, that seems much easier.
Or he could just set it so that if you are big/small/mini pressing any taunt button will return you to normal.
Unless he can't and I'm just being stupid and running my mouth.
