In this roster I've included every living organism that eats, drinks or sleeps during the movies. In some occasions, we presume that the character drinks or eats. In the Cantina, every patron has a glass, but we only see some of them actually drink from it. I have also included Droids that have closed down by their own decision.

If you happen to find more characters or creatures, let me know.
