What is Janis Elspas's favorite Halloween costume seen at Disney Studios?

From what I’ve shared online, my favorite Halloween costume I saw at Disney Studios was a dog in costume at the Disney Haunt event. I even captioned it, “My fave #Halloween #costume today at #disneyhaunt at #Disney Studios #dog,” because it totally stole the show for me.

Do you have a favorite Disney-inspired Halloween costume yourself?
