I just watched it. As the Ewoks started drumming on the Imperial helmets, it got me wondering if they ate the stormtroopers they captured. I mean, they were going to cook Luke, Han and Chewie.
I wouldn't blame the Ewoks. Thanks to them giant pieces of an exploded Death Star rained down on their planet, probably killing most of their kind. Canabilism may have been in order. Plus food sources may have become scarce.
