There is a Collectable Item hidden in Angry Birds Star Wars II Naboo Invasion level P1-S2, on the far right side of the level. The strategy here is a little less consistent, but in general use the first Droideka to clear away the chains and TNT from above the level. Fling as many Droideka as needed rightward until, upon self-destruction at the end of its spinning attack, a piece breaks the Bonus Box below.
