I love the Ewoks. They follow up the lessons we’ve learned of size not mattering and how your eyes can deceive you as we can also imply they roasted and ate the stormtroopers. So they’re more dangerous than they entirely appear. It’s just like the Gungans in a way. Nobody takes them seriously until Jar Jar steps up. The Gungans and Ewoks really juxtaposition each other. In a larger general sense Obi-Wan’s lesson is rooted in what Qui-Gon taught him with valuing all life and Yoda was speaking from experience.
