"Bewhild", I am fairly sure, comes from a base of "bewilder" meaning "to perplex or confuse especially by a complexity, variety, or multitude of objects or considerations." With three heads, this creature does not only bewilder us humans...but probably itself as well. Just imagine, "It's my turn to eat today! You ate yesterday! I'm thirsty, no I'M thirsty! Feed mee!"
