How should I know?!
Whenever Bowser shoots the giant spike balls, you suck them up with your poltergust 3000 (vacuum cleaner) and shoot them at bowser's head. Then King Boo comes out and you suck his hp out, and beware of Bowser shooting ice at you. Keep doing this and you will eventually beat him.
You can get out of Bowser's body when Bowser gets shocked by the security system in the Toad Town Caves.
Yes, all Nintendo ds games work with the dsi.
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 Bowser by studying his forms carefully and that golden Bowser block well you kick and punch it so if you have that game write this down and go beat Bowser!
no, I beat bowser (bowser jr.'s challenge is to beat bowser) in sudden death 3-2.
keep hittin him with a hammer and special attacks
If you have NSMBDS, and you beat Bowser in World 1, you will see that when you hit the switch, Bowser falls into the lava. This is how Bowser becomes Dry Bowser.
in the twins room once you beat the twins.
No because Mario is more powerful than bowser!
You don't
you have to beat them (final boss) then bowser Jr. and metal sonic (after beating eggman & bowser and after you complete all their challenges ) then beat eggman and bowser again the they will "follow" you.
