Velvet, our friendly neighborhood Little Mermaid collector and Sneak Peeker Extraoridinaire has checked in to let us know she found this snowglobe superball at a Disney Store. We've mentioned these before as being available in Europe and I saw similar non-Disney ones around Christmas time here in the USA, but this is the first sighting of Disney ones in the US. Velvet reports that besides Ariel, they had Cars, Cinderella and Buzz Lightyear for $3.50 each.
These are not hard superballs with a figure encased in the rubber. They actually have liquid inside with the figure and glitter and operate just like a snowglobe except they are also a superball.
