If Toan missed the Candy from Claude, he can also obtain one from Couscous. If Toan refuses, he'll hand over a Fire or Ice weapon attachment, and if that is refused he'll hand over the Turtle Shell. If the candy is missed from Couscous too, the Sun weapon attachment is lost forever.
The next item is also found in Matataki. Toan must give the candy to Bunbuku, who ate Kululu's candy. In return he'll give up the Ointment Leaf, which can be made into a cure all medicine, akin to Lao Chao's Miracle Dish.
