Ewoks were short, furred people that lived on the forest moon of Endor. They were extremely primitive, and spoke Tagalog, a dialect from the Phillipines. They occasionally had dealings with people, but mostly just hunted and got eaten by really big nasty monsters.
Then the Empire built a new Death Star over their planet, and the Rebel Alliance had to come blow it up. The Ewoks were skeptical at first, but ultimately helped and even rescued their new human friends. They won the day, but then had to deal with bits of Death Star raining down on them.
