I've seen these creepy things around before and did not know what they were and, for the life of me, I cannot figure out why they are popular. To my, possibly jaded, eyes, they just look ugly and elicit a very negative response. I learned that they are actually supposed to be ugly in such a way that you may, if you look at them long enough, decide that they're cute. That is, if you don't want to blind yourself before you reach the point at which madness overtakes you and you decide these aesthetically displeasing creatures are attractive.
Someone decided to put illustrations of these on cookies. These are called "kobito (dwarf) zukan (encyclopedia) biscuit". I don't know what Kabaya was thinking unless it was, "if I eat all of these cookies, those horrible faces will go away." No, I did not buy them. I'm sure they're boring little cookies anyway and I wouldn't want one of those things in my house.
