Level B1-S1 (Naboo Invasion)

This level can be unlocked by obtaining the Treasure Map in level B1-6. To finish this level with 3 stars you'll only need one bird. Fire C-3PO towards the middle of the level, breaking him almost immediately after launching him. The TNT on the left side of the level should detonate. If you're very lucky, the wooden object should fly to the right and fall on top of the TNT box. This should make the TNT box fall down and create another explosion. If you're not able to do this, use a second bird to finish the job. Feel free to add a comment when you've got a different strategy.
