One non-character swap strategy for Angry Birds Star Wars II Battle of Naboo level B3-18 is to send Jar Jar at a low arch towards the top left pig hanging from the rope. A good distance away grab the rope with Jar Jar’s tongue so that he loops up over the top and flies into the bridge on the top-right, causing it to fall. Now, let me warn you, this level is extremely difficult to 3 star naturally (worth the effort though!). The key is that the tank blow up the TNT at 9 pm before it falls. It’s also critical that pretty much everything be destroyed, which includes the TNT on the far bottom right of the level. The score in the video is 100,110.
Alternative Highscore Strategy
Since this level is so incredibly difficult, we have an alternate strategy to help out. Send Jar Jar just barely above horizontal (if sent too high, the tank will shoot above the first tower). Grab the rope very high, near the wooden plank (too low lacks stability). Release Jar Jar to go through the wooden base of the tower, below the tank, and into the TNT beyond. The biggest variable is whether the piggy inside the tank is popped. The score in the video below is 104,010.
