Here's the very short video I took of the item in action. It's a fairly crude video since it was taken on my phone, so apologies up front for that, and ignore the people in the background and such since they don't figure into this.
Who in the world thought this was a good idea? I mean, I know spinnies are quite popular, and Disneyland has a ton of different styles. But a spinnie that has Minnie's dress flying up and showing her undergarments? That's just wrong. It really makes me wonder if the merchandising department thought this through at all.
