You have to defeat Bowser with Minny Mario on the last level of world 5.
Believe it or not, he doesn't really have a last name, The only time he ever did have a last name was in the movie (Which really didn't reflect on Mario at all.) Super Mario Bros, where his name was Mario Mario
First go to the world 3 last castle or world 6 last casltle if you are mini mario, then you beat bowser there is a little hole and it leads you to world 4 and 7.
The way to get the last star coin on New Super Mario Bros W6Tower 1: first you have to become mini and then jump on a dry bones, and then do a wall kick. You will then land on a platform with a green tube. Go through it and then you will encounter a bunch of traps with spikes (first featured in W3 Castle). You jump (Please be careful!) and WHAMMO! you have the 3rd star coin! I hope you try it out!
Its easy(you have to have unlocked mario and the power flower) . Go to the room that you got Luigi in(upstairs, the last room on the right) goto the end of the room. There is a red coin there but dont fall down the hole.Go in the door and you will see a ! block. use it to float across the room and get the red coin.
By getting every single Star coin
knock down all of the star coin signs
it is the last world in the game
you should get the action replay
There hasn't been a Super Mario Bros. title exclusively to the DSi because all of the Ds systems are the same, they all play the same games, nothing is different.
you have to shrink yourself and where the guy throwing the boomerangs you kill him and you get on the little bridge and bounce from side to side.
