There is a Treasure Map hidden on the far right hand side of Angry Birds Star Wars II Battle of Naboo level P3-16. This map piece is difficult to obtain, but fortunately each of the three (little) pigs will follow the same trajectory.
Lob the Emperor at a high arch so he comes down just to the right of the boat’s mast. As he passes the sail fire his lightning to to the far right to destroy all the blocks stacked in front of the map. Darth Maul doesn’t really do much, but fire him on the same trajectory so as to maintain the path for the next shot. Lastly, with the blocks in front of the map out of the way, lob the Emperor and as he comes out of the water use hit lightning to grab the map. Once the Map is collected, the P3-S3 and P3-S4 Side Quests will be unlocked, earning you access to two more levels.
