Got one when I was there in May. It's basically a small plain sand pail and shovel, with no decoration. They fill the bottom of the pail with french fries and top it off with chicken strips (fried, of course).
I can't remember how much it cost, but don't think it was much more than a normal kids meal (at least I didn't feel like I was getting ripped off). At least it gave my 2-year-old something to do while we ate. I think the handle on the pail broke off in the hotel room and it didn't even make it home...
