The fable characters depicted by these emojis can be met in real life too. When I was in a kindergarten, we had Santa visiting us. Some people do truly outstanding things — they are wizards. Other creatures are so silly and childish, that big human ears don't save them — they are still elves.
"They are all not real!" — you would say. Maybe you are right, but personally I tend to come across some realistically-looking zombies and vampires in our neighbourhood, especially on Friday nights.
