Instructions
Destroy everything. Press the "B" button to attack environmental objects such as flowers, houses and trees. Each time you successfully attack an object, studs will drop which you can then walk over to and pick up.
Find objects on which a white ring symbol appears as you walk past them. You can use the force on these objects by pressing and holding the "Z" button. The objects will then move around the level by themselves and drop studs when they land on the ground.
Search the level for blocks and small objects that appear to be jumping up and down by themselves. If you move your controller and nunchuck back and forth standing next to these pieces, your character will use them to build an object. Once the building is complete, a large amount of studs will be added to your count.
Look for objects that appear to shine. These can only be destroyed by a bounty hunter's bombs, so when you find them press "1" or "2" to switch your character. Find a character like Boba Fett and press "Z" to throw bombs at the shiny objects and earn studs.
Enter all the vehicles and ride every animal by pressing "C." You'll see a series a blue studs appear in front of you. This happens for every vehicle you enter, even the ones you build out of blocks around the level.
Walk everywhere. There are hidden flower beds that appear and give out studs when you walk over them, so traverse the entire level before you give up. After you've done everything, you will have earned one million studs.
