In Oops there were things like A Girl's Wish, Black feathers, and then new things like A Boy's Dream, Pirate Towel, and Golden Eyepatches. I would instead bank on new drops for mermaid little and the fish guardians (Or making use of existing but currently unused drops), possible new Witch drops, and a new dig item for Lethos. Thus far from what I've seen Lethos' initial dig request is a new item (Stone Ginseng in Oops, Copper Nora Stone in Ghost blue, etc).
That said, thanks much kale, as it still gives us a direction at the very least.
this is the list based on what was added on kTO, and so far the only difference from the kTO and eTO quests is the siremaid card to scale switch.
so based on that history the waterweed witch card is the only truly questionable one.
