There is a Collectable Item hidden in Angry Birds Star Wars II Escape to Tatooine level P2-13, in the top-right corner of the level. Use Count Dooku to take down as many bone pillars as possible, including the bridge in the middle of the level. Fling Darth Maul wherever he is needed, then send Count Dooku straight ahead. Aim the boomerang lightsaber nearly vertically through the gap to reach the Bonus Box.
