How do you get Wario he is the only charecter I need!help!?

To release Wario, you must do the following:

1. Collect 30 Stars and gain access to the Star Door in the basement using Mario.
2. Enter Dire Dire Docks and complete the mission 'Board Bowser's Sub'. Once you do that, the liquid wall in the chamber behind the Star Door will recede to give access to Bowser in the Fire Sea.
3. Clear Bowser in the Fire Sea and defeat Bowser by tossing him at one bomb. At the start of the match, Bowser will attempt to throw you off the platform by jumping and causing the platform to tilt, making you slide down, so get as far away from him as possible before he jumps. The platform will also tilt when Bowser comes up after you throw him over the edge. Bowser will also disappear and transport to another area on the platform, so try to grab his tail and toss him quickly. Defeating Bowser will yield a key to the upper floors of the castle.
4. Make sure that you have rescued Luigi. If you haven't done this, do it now.
   • Go to the chamber in front of the locked basement door and follow the Boo outside. Collect all of the red coins, which can be scored by killing the Boos.
   • When you get the Star, go back into the castle and return outside. Go to the Boo to your left behind the fountain in the lawn; when you get close it should become transparent and reveal a cage. Defeat the Boo to enter.
   • Go to the upper floor of the mansion and enter the Luigi painting. Clear the level and you should appear in a room with a mirror. After a few seconds of running, Luigi should appear in the mirror with Boo behind him. The objective of the challenge is to locate and attack Boo using the mirror as a guide, as Boo will be invisible. Defeating Boo will yield a key to Luigi's door.
   • Go to Luigi's door behind the 1-Star Door on the upper landing in the castle foyer and enter to release him.
5. Unlock the door to the upper floors and proceed.
6. Go into the room with the mirror (the entrance to Snowman's Land) and grab a Power Flower. Run into the mirror and you will have control over the reflection. Going through the door at the back will yield a secret castle Star, but going through the Wario painting will lead you into a snowy level.
7. Clear that level and defeat the Ice King by pounding him toward the edge. Each time he goes over the edge he will come back up and bounce about, causing sections of the platform to fall into the icy water. Continue pounding him until he starts collapsing sections, at which point he will give up and yield the key to Wario's door.

You need about 35 stars.
