There were the characters (!!!!) and there were rollercoasters (!!!!). But the girls’ second-favorite pastime was collecting pixie dust, little sparkly Mickey ears that are strewn throughout Magic Kingdom by park employees. Other than meeting Sleeping Beauty, there was nothing that Sophie would rather do than find all the pixie dust she could. Chloe did it, I suspect not so much because she liked doing it, but because it annoyed Sophie when she collected them too.
Needless to say, Sophie contributed quite a bit to the cleanliness of the Walt Disney World empire (and she has a huge pixie dust collection to show for it). They also turned the walkways into obstacle courses, especially for people who were trying to steer strollers.
