Well, I didn't
need to get Minnie's costume, but I did want it.

And I was able to get all of her fabric without slowing down the process of getting what I needed for Li Shang. (I didn't send Mickey for her fabric until I after had everything I needed for Shang.) In the same vein, I'm still collecting tokens to level up Elsa (from 9 to 10) by sending all the Frozen characters after her items rather than collecting dragon currency for the Mulan event. I'm getting plenty of dragon coins from other characters, so I'm devoting the Frozen crew to where they can do more good, if that makes sense.
