I just watched Return of the Jedi, and while I am willing to accept that there is a lot about the Endor Forest Moon battle and the Ewoks in general that doesn't quite add up1, this watching left me wondering just what the Ewoks had been planning for.
It is reasonable to believe they could have setup some of their simpler traps in the short time they had to prepare for their offensive & rescue of Han & Leia at the shield generator, the speeder bike "clothesline" for example, and maybe even placement of their wood catapults... But what about the larger traps like the rolling log pile or the two huge swinging logs used to destroy the AT-ST's?
Is it possible the Ewoks were already planning a revolt against the Imperial presence on the Forest Moon? Or if not against the Empire, for whom were those traps set?
Addendum: Just to note - It occurs to me that they set mostly defensive traps rather than offensive ones.
1.Like, why do they build huge bonfires in trees, mere feet from their thatch huts or on/near their fragile rope bridges?
