This has the exact same format as LEGO City, except the town is different, and some new things are added. Here are all the studs you need, starting at the merry-go-round and going clockwise around the edge:
Studs on the ground
Destroy all characters, womp rats, etc (Gonk Droids and still invincible)
Destroy the fence and the trees
Blow up the metal container with a thermal detonator, use the pieces that spit out of it to build a rotator switch, and push it. This causes the merry-go-round to spin until it flies off from the ground
Destroy more fences and the trees
Collect the studs on/around the playground, slide, and swings
Hop on the AT-XT and blast the church a few times
Destroy another fence, more trees, and plant the blue flowers
Destroy the fence around the dewback
In the water area, kill the fishing stormtroopers and the ducks
By the boat, build the push block, and use it to push the boat into the water. When you start to drive the boat, studs will appear on the water. Collect all of them while driving
On the white and orange service station/garage building, use the Force on all of the windows, smash some of it up, and collect the studs in the right garage (you can open this by pulling the two levers on either side of it)
Plant the orange and yellow flowers
Destroy more trees
Destroy the chairs in the garden
Bloom the flowers with the Force, and then destroy their pots
Destroy the fence around the church
Use Sith Force on the door on the church to get inside and collect the studs in there
Bloom 19 blue flowers (15 on one side of the church and 4 by the front door) by stepping on them. You can barely see a few blue specks where the flowers will bloom once you walk over them
Build the top of the church, enabling you to pull a lever, which rings a bell, giving you studs
Go back to the service station and destroy the bus stop and the trees in the area
***You do not get any studs for this, but it is pretty cool. You can jump on top of the floating house by riding up to it on a bantha, and then jumping up on the roof. You will then get carried up to the sky***
Collect the studs inside the house frame for the floating house
Blow up the metal container inside the floating house frame with a thermal detonator, and build the resulting pieces into an orange car
Destroy the next fence
Collect the studs inside the empty house frame, then destroy the trees around it to build the house
Collect the studs behind the land speeder
Use Force to bring a house down, then destroy its frame, which gives you pieces to build a mini-house
You can spell "LEGO" again with the blocks, but this time, the letter are out of order, and the order to stack them is not already determined, as it was in LEGO City (if you need directions on how to make each letter, see the Right Room summary in Bonus Level 4 - A New Hope). The first letter is G, then O, then L, then E. Once the letters are constructed, you and the CPU can use the Force to switch the "GO" and "LE" around to finally spell "LEGO"
Drive the firetruck, and follow the path of blue studs. Once you collect all of them, the truck will stop by the church. Use the Force on the ladder of the truck, which will create a grapple point up to the top of the church. Grapple up to rescue and cat
At the red service station/garage building, use Force on all of the winders and doors, and smash it up a bit. Also smash up the blue flowers in front of it
Repair the windmills with the Force
Blow up the small yellow house in the corner with a thermal detonator, and then use the resulting pieces to build a tractor
Destroy the fence around the house with the black roof, destroy the house itself, and collect the studs inside of the house frame
Use Force on the large trophy 4 times
Destroy the next house with a thermal detonator. There are studs to collect inside the frame
Go near the starting area and collect the studs on the road
Plant the plants by the red and white house with trash cans by it
Destroy the trash cans, which will spit out pieces used to build a truck
Destroy the house itself
Destroy the taun-taun fence
Ride the taun-taun, and collect the path of studs that pop up when you get on it
By the power lines, push the rotator switch to push the cart on top of the lines to the other side. Now, hop on it using a taun-taun, and wait for the cart to return to its original place to collect the studs above the powerline
Go to the basketball court, and collect the studs underneath the bleachers
Destroy the fence and the people by the court
Shoot the ball in the hoop once
Plant the flowers in the area
Blast the overhead lights (a lightsaber attack will not do it)
If you still need any more studs, hop on the AT-XT in the back right and start shooting everywhere
