Rovio released a new trailer today for Angry Birds Star Wars, featuring an avian Yoda. The video highlights the Path of the Jedi levels, which can be purchased in-game.
Anyone who has already played Angry Birds Star Wars has seen the tempting Path of the Jedi levels, with the crashed slingshot-X-wing on top. After the introductory level, a message pops up, selling the levels for $2. However, Rovio stated in the trailer below that 3-starring all of the other levels in the game will also grant access to Dagobah.
When the Path of the Jedi levels are all beaten, the Luke bird gets his lightsaber upgraded. From the video description:
Once you've made it to Dagobah, beat all 40 levels to unlock the green Lightsaber - It's more powerful than the blue one, and Luke can use it throughout the rest of the game. Yay!
Of course, if you 3-star all of the other levels to unlock the Path of the Jedi, there won't be much else to do in the game after obtaining the green lightsaber. Players will have to wait until the Hoth update is released for new content. Then the Wampa limb removal can begin.
