There is a Collectable Item hidden in Angry Birds Star Wars II Naboo Invasion level B1-S2, under the slingshot platform in the water. To obtain it, fling R2-D2 into the ledge above the water so he bounces back into the Bonus Box.
Go back to the Complete Star Wars II Bonus Boxes Guide. If you have a different strategy feel free to leave a comment below.
I was trying to get the bonus box on B1-10, but I’m playing on a small smart phone and the TNT box does not show. I used Jar Jar to swing around and got it.
