Paper Mario: The Thousand-Year Door Tips

Easy method of beating the Shadow Queen
This is the easiest way I know of to kill the Shadow Queen. Buy as many Boo's Sheets as you can carry (but it wouldn't hurt to have an Ultra Mushroom, for backup.) They can be found on the Excess Express shop for 20 coins each. Equip yourself with the Charge and Power Bounce badges, then go to battle. During your turn, charge up and let your partner use Boo's Sheets on you. It doesn't matter if your partner dies-they're not important. When your supply of Boo's Sheets run out, use Power Bounce. You can easily deal over 100 damage in one turn this way. (This trick will also work with Goombella's Multibonk.)
