Magic Mirror
If you want to get a new Bro.'s move, go to Bowser's castle as Mario and Luigi. You must have gotten the abiblity to suck up air and fly. Go to his castle and go to the right of the main loby. Follow the path untill you get to a place with 3 buttons. Hit the buttons in this order. Square: twice, Circle: once Triangle: Three times, then hit the button on the door. In the next room, MAKE SURE YOU ARE AT FULL HEALTH! Hit the red button at the left, and FACE THEM SHROOBS. Once you win (watch out, this might be a bit hard) then you get 10 bro.'s pieces and now you have the Magic Mirror.
