Been eating this by the box since college, so no one knows the "green smile" (was The Green Slime the movie with the mystery alien woman whose name wasn't even revealed in the credits, because that always creeped me out) like I do, but last night I must've pushed a piece of 青海苔 under the gum above my front tooth brushing afterwards and took nearly half-an-hour of careful flossing to extract it.
