Why do the Ewoks have soap and what makes it so “special?”
For sanitary reasons alone, the problem had to be dealt with. The technological base and physical morphology of the Ewoks ruled out such solutions as mass burial or cremation, while their hunter-gatherer society placed a high value upon resources that were difficult to obtain otherwise.
So that’s how the Ewoks ended up with storage hut after storage hut filled with “special” soap.
