Hello my name is, sticker, labeled Dwight.
Winnie the Pooh,
A Goodwill red shirt, a couple yellow towels, some blue fabric,
headband and pipe cleaners to make ears with some of the extra towel fabric.
some sort of Honey prop
Clear umbrella, bubble wrap, all white outfit
Toy snakes wrapped through braided updo.
