You take for instance the Krayat dragon call. That’s one of the sand people not a Krayat Dragon, Obi-wan is not making that sound… It is absurd to think so. it’s probably just missing the close up of a tuskan raider reacting to the old man approaching.
What are you even going on about. Of course that was Obi-wan that made the howl. Are you insinuating that Tusken Raiders are so dumb they spook themselves?
