"Colorful dango that look quiet appetizing. It is said that the colors were chosen to please the Gods. Perhaps that's why these precious dango aren't edible."
Tricolor Dango is extremely poisonous to Oni. "When eaten, within 10 seconds, you'll be writhing in pain. All of your muscles will strain and tear, you'll throw up your entrails, and blood will gush out from your body like a waterfall." - Gatekeeper Kenshi, during Kikuzou Dango Quest.
