I'll tell you but you can find more info in the new Super Mario bros wii guide book located in GameStop. But anyways, you avoid all the spinny spiky overkilly things to jump to the different platforms to get to lugwig. well that was after the checkpoint. before the checkpoint its easy and you should be able to figure it out. after that you go to fight lugwig. he may be hard for you, but he wasn't for me. you stand on bricks. then magikoopa does a spell to make three elevators pop outta the ground. he'll shoot you with beams and you have to Dodge. then, he'll fly up in the air and land on a random elevator. that's your chance to hit him. never stay on the same elevator as him or you are DEAD. after that just hit him two more times and you are done with that world. If you want hints for the other world bosses, than keep reading. WORLD 8- fight some levels then the tower. the tower boss is magikoopa. after beating him, you go through some more levels to fight bowser jr. in the air ship.(ground pound the ground to send a bomb flying up to him, then BOOM!) then a giant, and I mean GIANT castle pops up. enter. you'll know how to beat it, but it's tricky to do so. then you go down the hallway to the boss, where fireballs are blasting at you. then you fight bowser. wait till he jumps really high to go under him. hit the switch. he falls and dies. you see "peach" crying in a cage. turns around and you see magikoopas face.creepy. he does a spell. he sits in the middle waiting. waiting. waiting... BAM! Bowser pops up GIANT! kills magikoopa. this is where it gets epic!>:) he'll shoot big fireballs at you, you dodge, they'll blow up the wall. they'll anihallate anything they touch. ANYTHING! after a heck of a lot of dodging, if you are at least normal size, not midget mode, hit a block and a propeller shroom pops out. grab it. use it. hey, guess what? more DODGING! Oh, and this time there are lava tidal waves racing after you! (you can thank bowser) hit a switch like the first time, except its bigger. you finally save peach. when you're in the hot air balloon that luigi gives you, peach tells you about something you would never expect... another world!!! WORLD 9- a special world. I haven't even completed a level because you need all the fricken' star coins! hope i could help!:)
There is NOT SUPER MARIO WORLD Wii...
There are 9 Worlds in total. To get World 9 you have to beat the last level of World 8 which is Bowser's Castle.
You can't.
You have to beat the Level 5 castle in mini Mario form.
Well, avoid the koopaling attacks when he ground-pounds by jumping. When he lands, I suggest you jump on his head right away.
if you mean new super Mario bros, then you beat world 6 castle when you are mini Mario.
beat the castle in world 1
You beat it.
beat the last boss in the last castle in world 2 as mini Mario
Beat the boss at the end castle on level five as mini Mario.
beat bowser castle after the ship
All you have to do is go to the world 2 castle and beat the boss with mini Mario
You avoid the Goombas and try to get a mushroom if availible
Stomp on the spiky thing three times
You have to beat Bowser as mini Mario on the big castle on world 2 and 5!
You beat the game when you are in Bowser's Castle in World 8 and beat Giant Bowser and Bowser Jr. Then you save Princess Peach.
you beat the world 5 castle being tiny.
