Basically, all of the items in there are food. For Wave 1, the figures that have food as a Shop selection is Ringotchi and Kuchipatchi, wave 2 is Sebiretchi and Ichigotchi, in case you need to know. The rest are Game, Shop and Item.
Nevermind about the yule log. At first I didn't know that they were referring to the food. I thought they were referring to the piece of wood that you use to burn in the fireplace. But now I know.
