“DEADFISH” is not one word. “KNOCKNOCK” is not one word. One a scale of easy, medium, and hard, “DUNGAREE” is not hard, but impossible. How many people have ever heard of the word dungaree, much less be able to recognize a drawn depiction of it? Lastly, on a scale of easy, medium, and hard, “MOJOJOJO” is not a word at all but the mating call of a lunatic.
