Why did the Jedi Mind Trick (JMT) not work on Watto? There is an excerpt from Wookiepedia which states:
Similar to the Hutts, Toydarian brains have an unusual composition which made them immune to influence from the Force.
Is this the actual reason? Or is it because Watto has the superior mind Obi Wan talks about in A New Hope?
BEN: The Force can have a strong influence on the weak-minded. You will find it a powerful ally.
Or is it something else altogether? What makes the Toydarians special?
NOTE: There is some overlap with this question here, but I believe the actual question is quite different in nature, as it's about Watto and the Toydarian race.
