In Star Wars
In the Star Wars film series, Tatooine served as Anakin and Luke Skywalker's home world. It was a desert planet that had frequent sandstorms. The majority of inhabitants were poor and farmed moisture and sold mechanical parts for a living. Tatooine has been looked down upon by most other planets, because of its high criminal activity. Activities included gambling, robbery, piracy, and more. Some areas on Tatooine were ruled by a species known as the Hutts, most of them known to committ numerous crimes.

Trivia

 * 1-1 through 1-25 use the gameplay as established in Angry Birds, while 1-26 through 1-40 use the Angry Birds Space gameplay.
 * 1-37 through 1-40 actually take place in the destroyed Alderaan, rather than Tatooine.
 * The appearance of a lone TIE Fighter pig in 1-40 is an allusion to the movie, where Luke and the others follow a lone TIE Fighter from the destroyed Alderaan to the Death Star.
