How do you find bowser and free him from the safe?

Bowser is in peaches castle. You have to find the last sage which is on plack beach on the cliff. Birdley will guide you there. When you reach the sage, He will tell you to make him fallover. You then try but fail. He then tells you to go to dimble wood and get all the attack peices there. Get 6 attack peices then talk to the wiggler left of Broque Monseiurs shop. He will let you pass and warn you of danger. YOu go in the next area and mario goes little to open a gate to let luigi through but mario is captured by 4 sockops! You must be luigi to save him. Go through several areas until you reach an area with a giant sockop. You will automaticallly jump in and do a fight. After that, Mario gets chugged. The sockop will shrink so you can't get out of it. This means you can walk across thorns and get 3 attack peices.Then go north and you will find 3 sockops, the last attack peice and an unconscious mario. A scene initiates where he wakes up and you fight the sockops and get the attack peice. Go back to plack beach and use this new attack to make he sage fall over. He will give you the last star cure and send you back to toad town. Go to the clinic where the docter will make the miricle cure and cure the blorbs. Then go to the blockade and into peaches castle. Do it until you reach the junker boss, where whenever he gets luigi jump on his head until he releases him. After this boss you will find bowser.
