I was told you need to trade moogle all 8 items for best reward 7 being different combos with races and gender and then keeping your own item once to make 8
I've attempted this one personally. I had all eight items from doing the last run twice and not tradeing the second time. And I can confirm it does nothing at all. The moogle will simply take the first item you trade amoung the eight and accept it as a single offering and you get more food.
Also, it's not possible to turn in multples of the same item as you can not carry multiples of the same item. Additionally you need the key item of the drawing for each turn in, so you can't beat the system by having someone else trade you a second item, it won't work. Trading the food rewards to either mogs, festivle mogs, nomad mogs, or the special event salespeople, even the goldfish game sales lady have proven fruitless.
My theory is that SE has simply not released the 'real' event items. Long time players know very well that SE has a knack for screwing around with events, giving us lame rewards for a few weeks, even for half the length of the event before letting go with the good stuff. Keep trying, at least the event is relatively fun and painless this year.
