Death Star 2 6-30

Death Star 2 6-30 is the final level of Death Star 2. To pass this level with three stars, you should defeat Emperor Piglatine and score at least 57,000 points.

Strategy
Fling Red above the first moving platform, followed quickly by Obi-Wan pushing the blocks immediately in front of the slingshot platform. Launch Stella as soon as possible toward Piglatine and pulling the wooden wheels in the top-right corner. Hopefully, Emperor will be hanging on by only a thread, thereby arming Lard Vader for the final launch. Vader can be flung multiple times until the Emperor is popped, so get some extra damage points before destroying the Empire.

Trivia

 * You can use Darth Vader unlimited times in this level when you damage Piglatine enough.
 * This is the only boss level in Angry Birds Star Wars where you earn 10,000 points for finishing boss.
 * The music stops playing when Lard Vader is joins the bird side. If the player replays this level in this session, the music will not be played.
 * If Vader jumps on the Slingshot while another bird is jumping on the slingshot in the same time, there will be two birds on the slingshot at once. Trying to shoot the bird from Slingshot will crash the game.(To perform this player needs to quickly launch a bird while Piglatine is already defeated, before that bird jumps out of slingshot to make place for Vader.)
