Easter Egg!!!: (you Will Need two controllers and a jedi) in the retake theed palace level, go into the room with the two fountains, turn on the second controller an have both characters use the force on the fountains, When the fountains are done going on and off there will be rainbow bubbles.
The machine was supposed to launch Lego bricks but it failed many times. I tried a Lego guy and he got clamped inside because the seat for it was round. I tried it again, and it worked! About the "dang" sorry I could not find the right word.
