I think people might be confusing the term "humanoid" with "bipedal".
Hork-Bajir are bipeds, which means they have 2 arms, 2 legs, 1 head, 2 eyes, etc. Well, not necessarily all of those, but the 2 arms and 2 legs bit, at least. But being bipedal in itself doesn't make one humanoid.
there you go. that's the word i was looking for.
