Depending on where you live, we could band together and storm some meetups until K-con comes around again. I'm also hoping to pull together an alternate Fireball Mario (white overalls and hat) cosplay. The items I would have in the ? block are:
Fireflower, in the shape of a cup and a soft orange ball that you can throw out of it.
Star, with a golden poncho inside
Red Mushroom,
Green Mushroom,
a bag of fake gold coins,
A leaf box with brown ears and raccoon tail inside,
A feather box with a yellow cape inside.
As far as height goes, I can be Super Mario!
