Hit the red SWITCH.
A power brick is a red Lego brick hidden in each level. They unlock extras to buy
in world 1 at the tower there is a red flag that you need to get to unlock the cannon.
You can't get the red star in super mario galaxy 2
there red
Since the switch is under a red brick, you need someone who can punch; that is, Mario, Luigi or Wario.
You can get the spells by using the character detector from Diagon Alley after you unlock it as a red brick.
you can unlock a level with a pipe and cannon around it (i got it on a red flag on world 2 number 4 ) and finish that on a cheat flag( the yellow pipe above the other 1). this will unlock the cannon.
You must get the Blue and red Key from the Jabbies and unlock the Cage doors.
what you have to do is unlock the red boxes. then if you're Mario if you hit one a feather might come out. grab the feather and you can fly!!!
Depends on the size of the red brick
All you do is get a mini mushroom go into 2-4. Go all the way down to the water, go left through the pipe and you should see the red flag which should unlock the mushroom.
u don't have a code to unlock it u unlock invincibility by buying it when u get the red power brick with it,then go to extras and say yes to invincibility
