It's October, and you know what that means. Well, yes, you could answer "Halloween", or
you could answer, "pictures of Mickey and Minnie in spiffy costumes". Either one is equally valid at this point.
Let me explain right away that these costumes are not of my own design. Disney Store Japan's Halloween theme this year is called 'Wicked Goo', and involves mildly monstrous versions of the Sensational Six (really eight, since Chip and Dale get included, but shh).
I'm fairly certain that Mickey and Minnie are actually meant to just be a cute-looking demon and witch, respectively, but as far as I'm concerned, they are a Goblin King and Queen. To that end, I added a pair of Girly Horns to Minnie's design. That's my only contribution though; the rest of the ensemble was just that awesome to start with.
