how do you get to the last boss on the new super mario bros game for the nintendo ds?

Answer 1

ok let me remember. ok in the first area, dash until you get to the door, enter, get the powerup, reveal the switch, hit it and exit. now in the next room, go all the way to the right until you get to the door. enter, dodge the giant thowmp, get the powerup, reveal the switch, hit it, dodge it again, and go in the next door. now in the next room go to the left until you come to some spikes. jump, hit the lone block and the switch that comes out, and go back. now after you jump the spikes, there will be those two flamethrowers. dodge, then jump on the ledge. jump again on the other ledge and dash. when you get to the small flame, duck and enter the door. now dodge the mini thowmps until you get to the top. now fall, and hit the blocks that appear there. one will have a switch. hit it, go to the top, and to the left to get the star coin. now go to the right, dodge the thwomp, jump the spikes, hit dry bones and fall to the door. now go the levitating thing and jump to the door, now dash until you get the star coin. now go back and jump on the ledge and enter the door. you reach the checkpoint. yay. now go through the path. on the first one, just keep on running on the bottom. you will hear a ding, meaning you are going the correct way. in the next path, go on the top one. you will hear another ding. in the third one, go in the middle one. then you will see a star coin. ground pound the blocks, and jump on the ledge on the right. dash and when you get there, duck, and you should get the star coin. finally go back and the final doors will be there. enter. now the boss fight is exceptionally fun. kill baby bowser. then when you fight the big guy(bowser)do the following: if you are super mario or fire mario, all you have to do is run into him. when you downsize, you are invincible and can't get hurt so run right and hit the switch that will end it all. if you are regular mario(meaning you haven't got a mushroom), then you will have to do it the old fashioned way. when he jumps, go under him, and see if you live, hit the switch and you win. watch the credits and be happy.
