Star Wars Therilogy - Are There Ewaks?

Could you imagine something like that being done to the loss of the universe? Well, we don't think that it is any way for energy or mass to change those things. I just heard a theory that originally, mayby the ewalks were supposed to be wokis, but somehow they got changed at the end or somethingand i mistak a metisers did their job. That might be just a fan theory. Until then, i think saturn and the rest of the solar system are safe from being collapsed into two de objects for now.
