When you finish the game, you will unlock access to the Bonus Room. In the Bonus Room, follow all of the objectives to get the final 10 gold bricks. For one brick, you will need to get a million studs in the Bonus Room, without using multipliers to help.
In Level 4: Flatbush Rooftops, you will cross a bridge to a roof that contains a door blocked by rainbow bricks. If you use Unikitty to get inside, you will see Indiana Jones's hat, gun, and whip on a table.
You can get studs quickly by walking or driving through the hub areas and breaking things to get as many studs as possible. When you go to a different area and return, everything will be back in place so you can repeat the process. This is especially effective if you have stud multipliers active.
If you activate all of the five stud multipliers at the same time, each stud you collect will be multiplied by 3840.
To earn the "To the Invisible Jet!" achievement (Xbox One)/trophy (PS4), you must find and destroy Wonder Woman's invisible jet.
Go to the Cloud Cuckoo Land hub area in Free Play mode. Use Unikitty or another kitty to destroy the rainbow cloud bricks to your right. Use the rainbow bricks to build a launch pad, which will help you reach another cloud. Aim an attack, such as a boomerang through, at the air to your right. The jet will explode.
There are 20 Red Bricks in the game. Once you find them, you must purchase them with studs. Follow the instructions below to get them all. You should consider going after the stud multiplier Red Bricks first, as that will make it easier to buy the rest. Once you have a Red Brick, you can turn on its cheat effect from the "Extras" menu. Red Brick cheats do not hinder your ability to earn achievements (Xbox One) or trophies (PS4).
