Send Luke to the first pile of blocks, use a lightsaber to detinate the TNT (You must be careful if your lightsaber is upgraded.) This level needs luck. Send Han Solo to destroy the rightmost wood plank.
Send Luke towards the first sand-pig next to the TNT crate. Then aim Han Solos’ blaster at the pig attached to the steel plate above. This shot should ricochet towards the other pigs, clearing most of the level. Use a third bird if necessary by aiming the blaster at the top right platform.
