Welcome back! This is the walkthrough for level 11-20 Bird Side.
Naboo Invasion: Level 1-11:
Aim upwards, your target is the pigs in the water. When you are just above the water make Yoda pull his sword. You will bounce and destroy both towers.
Naboo Invasion: Level 1-12:
Make Yoda fly just right under the arrow sign. From there, he will bounce and destroy everything there.
Naboo Invasion: Level 1-13:
This one is a little tricky. Aim upwards and hit the stone I marked. Yoda will bounce and destroy most of the pigs. Use a new bird if there is still pigs left.
Naboo Invasion: Level 1-14:
Aim for where I drew the red marker. Yoda will bounce and destroy the tower. The rock will roll down and hit some crystals for you.
Naboo Invasion: Level 1-15:
Aim for the red marker. Yoda will bounce and hit the TNT on the upper right corner. Bricks will fall down and kill the pigs.
Naboo Invasion: Level 1-16:
Shoot at the stones on the right. Yoda will bounce back and fourth and kill the pigs on the left. Use a new bird as shown in the last picture. Aim for the wood to make the tower collapse.
Naboo Invasion: Level 1-17:
Aim for the middle, this will take care of most of the pigs. Use a new bird and use the force upwards against the upper pig. This will also kill the pigs underneath you.
Naboo Invasion: Level 1-18:
Aim for the upper pig. The crash will continue down and create a chain of reaction destroying everything.
Naboo Invasion: Level 1-19:
Aim for the first stack in front of you and use the force to shoot stacks against the rock on the upper right corner. If you manage to hit it, it will destroy everything on the map.
Naboo Invasion: Level 1-20:
This is the most hardest one in the Naboo Invasion level pack. The goal is to destroy the big pig vehicle. First, shoot Yoda to the lasers, one of the pigs is shooting. Make one of these hit the pig underneath by hitting them. Yoda will also bounce and later hit the ball on the left doing massive damage against the vehicle. Slowly this should also create a reaction on the right side making all the pigs die and some stacks fall down. Use a new bird and use the force to make some of the wooden stacks hit the ball on the right. It will roll down and eliminate the remaining pig.
