Yub Nub is way better and it’s also what Wicket says to himself when he scurries away in order to surprise the storm trooper so Leia can take him out.
It’s supposed mean “freedom” or “hurray” in Ewok language. It’s great.
I always get a little frog in my throat when the strings swell up and turn Yub Nub into an incredibly emotional moment as luke sees his father join obi wan and yoda.
I love it. I hate the change.
