If you look carefully you can find “Kobito” in the wild.  They are native to Japan and are magic, similar to leprechauns and so on. Some people manage to capture these little creatures and keep them as pets, as shown in the first photo.

Ha ha.  Just joking.  “Kobito Zukan” are actually a incredibly successful gimmick to get parents to spend money on stuff for their kids.  But they come in the form of books about the little creatures, so I guess that is okay.  Anything to get kids to read!
