Poringleaf can't choose, her fanbase must choose for her through popular portrayal! That's how these things go :V In the same fashion as Momiji and Daiyosei. (Then again, poring doesn't have a sprite we can work off of, but you get the picture.)
I think Kuma's arm-warmer things should have bear claws attached to them, that she can slip on and off like gloves without taking off the arm warmers. >:3
