Power Brick

Ch.2-In the first area, go to the far right of the screen and follow the rock wall until you see a gap with a heavy metal wall on the other side; you can use Boba or Jango Fett to fly across & use a TD or fly across with Artoo & self-destruct. Farther on, on the right, is a pile of rocks which you can hop up onto with a Jedi. Fly across (Fett or Artoo) to thge larger flat rock with a little cart on it. Push the cart off and follow it-it will crash through a barrier into a little cave, revealing the power brick.
Ch.3-In the first area (as you're starting) follow the wall on the left until you see a group of small trash cans; do NOT shoot them-use the Force on them until you have a jiggling pile of bricks. Build the bricks into a door and use Artoo to open the door, revealing the power brick.
