As I’ve said before, I think the Ewoks got tamed in the editing room.
If they were actually fierce, no one could have tamed them in the first place!
What I mean is they probably shot some scenes of Ewoks shooting down the troops and Lucas thought it too dark. Lucasfilm was so uptight about Ewoks being really violent they had Topps censor a 90’s trading card.
I guess they had no problem with the mace though.
