Question

How do I get wario in super mario 64 DS?

Answer 1

As Luigi, go to the second floor of the castle (you need to have beaten the 2nd Bowser),  Go up the spiral steps and enter the door.  Now go a bit to the right, in the direction that the bunny jumps.  You will see a door in a little alcove.  Enter it to find a room with a gigantic mirror (the room with the Snowman's Land course).  Because you are Luigi, there will be some power flowers on the small pedestals.  Grab one and walk through the big mirror.  On the right side wall there is a portrait of Wario.  Jump in and beat the level and boss to unlock Wario.

Hope this helped!
