For the moment, it's just available in your inventory or wardrobe. With our current system for adding items, I couldn't figure out a way to let you move it around outside of items/wardrobe. That doesn't mean it'll always be like this! I'll keep you guys updated, but when has a free moment I'm going to work with him about letting it move around your account (like TCs etc) but not shop/donating/etc. I thought it was more important to get the item out rather than hold off on prizes until we got that sorted!

(Why didn't we get that fixed during the quest-a-thon? We've been focused on backend things and quite frankly I didn't want to push big amounts of code while everyone's restocking for pirates, ha.)

Our intention for the item was to be used for the wardrobe. The prizes this time around were geared towards pet people (pet slot), battlers (challenger), and wardrobe people (hoodie). It wasn't until after we announced the prizes/started quest-a-thon people started to be vocal about wanting it to be in the treasure chests that we realized that the system we have it on isn't going to work for that. I was hoping there was a magical solution I could do when we started sending out prizes but there wasn't (hence my line above "With our current system for adding items, I couldn't figure out a way to let you move it around outside of items/wardrobe.").

That's why I posted above, that we're going to look into it. It's not the highest priority ( and I are working on some other things like Cash Shop revamp and Item Directory) but it will be looked into when has some free time next week. :)
