Lordy, this bit of Oz is quite busy.
I think the flying monkey in the hat is the one played by Zach Braff. I think the one with the trident is my next nightmare.
I assume that’s a munchkin in the hat. The character is called Knuck, and is played by Tony Cox from Return of the Jedi, Willow and Bad Santa. I’m no Ozpert though, so perhaps he isn’t a munchkin and I’m just being… erm… racist, I guess. How many diminutive peoples live in this place?
