Is 'grinch' a tag or specie?
The word 'grinch' has a harsh and hard sound, so it works as fictional slang for someone who bears the attitude of the titular character. However, it could also be what the guy literally is. He is called 'The Grinch', so Grinch is not his name. If the green person is a grinch, then not all of his specie are monsters because he is presented as a deviation. He looks a bit like a reptile, and if he is, then perhaps he has just made a notorious title for himself. Whatever The Grinch is probably does not biologically exist, but within the story, he has to be some type of creature.
