Other interactive store must-dos?

[mom2pixies]

So, I've heard about visiting Tink's Treasures shop (is it now closed?) just for the purpose of seeing Tink zoot around the shop or to peer into the keyhole of the armoire drawers to see little vingettes of Tink. And I've also heard about checking out the build-your-own light saber (Once Upon a Toy in DTD and Mickey's Star Trader in Tomorrowland) and build-your-own-dino (T-Rex in DTD) and build-your-own-race-car (Ridezmakers in DTD) stations in various stores. But I'm just wondering if there are any other cool, interactive things worth checking out in the restaurants and stores in any of the Disney parks? I'm not talking about artwork, props or décor necessarily (although great photo ops are good, too!), but more detailed theming--animatronics; special FX; occasional character visits; special freebies, tours, shows, experiences, etc.

If you know of one, I'd love to hear about it! Thanks!
