After what I presume to be my last trip to visit Uncle Mickey in the land of the mouse, I’ve finally figured out exactly what Pixie Dust is: cash, and lots of it. Sprinkle it around liberally at Disneyworld, and dreams really do come true. If your dreams are limited to overstuffing yourself, riding through It’s a Small World and purchasing themed T-shirts that make you look, well, Goofy.
