hey have the Darth Tater stuff at a shop near Star Tours. The other link had a lot of examples of the stuff they have. I don't know what WDW has, so I can't be sure, but I don't think there was anything specific to DL. Things that had ID on them, like an entry ticket, had both WDW and DL on them.
I got three sets of arms (wish I'd gotten 4); several kinds of feet and noses; assorted hats (sorcerers, princess crown, Mickey ears, Goofy, a Minnie Bow, a Mad Hatters hat, and assorted other), some small stuff like flowers, tickets, Mickey Balloon, suitcase, etc. Lots of little stuff they can hold. I think we got at least one of everything and multiples of most things except the Christmas tree! If I'd taken the time and hadn't had a 4 year old helping me pack the box, I'm sure I could have gotten the tree in, too!
If I could figure out how to post photos somewhere that I could link, I'd show you my livingroom shelf. For the past month it's been populated by my Mr. Potato Heads. The kids have fun rotating the decorations.
I'll try the link: here goes!
