There is a Treasure Map hidden on the bottom right of Angry Birds Star Wars II Rise of the Clones level B4-7. To obtain this map fling Mace Windu towards the main structure, and send his Light Saber to the right, and back into the map piece. Once the Map is collected, the B4-S1 and B4-S2 Side Quests will be unlocked, earning you access to two more levels.
