We did one of these a few years back. Some of the items we listed, OLC ended up making. Im not sure if we had any help in that, in case we did, lets do it again.
My list is
1. Bear size popcorn container for each season, we need a christmas, Halloween and Sweet Duffy
2. Bear size Lanyard with Duffy AP or ticket. You get the ticket when you buy your ap or ticket, maybe they can do it as a guest request as not every guest will have a Duffy. It would be great for the APers if you can have your Duffy photo on the pass and not just a generic Duffy.
3. New PJ set and Rain Jacket/outfit for Duffy and one for Shellie
4. Non Holiday,(if they do seasonal ones, do more then one season) more nautical themed Lesportsac bags with Duffy and Shellie, but not both together on every bag, a verity would be nice. The bears fit well in the Voyager Backpack, small and medium duffles and the carryall. On the material it would be so cool if it also had the buildings of Cape Cod
5. Snowbear Duffy and Shellie light up necklaces. and anything else Snowbear, they are cute.
