In the introduction, Wario and Waluigi walk by and look at the tournament board. On the bottom left-hand corner of the tournament board, you will see Toad and Toadette competing. However, they are not playable characters in the game.
Get as close as you can to the net while maintaining control of the volley, then when the ball comes to you, hit to the opposite end of the court... (If opponent is in left court, hit as far to the right as you can). This works best with characters with Tricky attributes.
To get Fly Guy you need to beat the tournament through Mushroom Cup, Flower Cup and Star Cup in one player with any character you choose. DO NOT pick doubles before you start a tournament if you want to get Fly Guy, only pick singles.
The difficulty levels in a tournament as you go along are: 1.MUSHROOM CUP- easy 2.FLOWER CUP- intermediate 3.STAR CUP- Expert ...* After you beat the whole tournament your character will become a star player in the records section showing that you've beaten the tournament with that specific character.
After you beat Mushroom Cup in the singles tournament you'll get to beat Machanical Bowser in the special game section.
To beat the game you need to become a star character with every character, get all the hidden characters and get all the Gimmick and Standard stages.
....* To use your power in a tournament or exibition your racket will light up. When that happens you hold down the R button and press A or B. Your character will either do a power hit if the ball is close to you, and if the ball is far away from you the character will do a special hit so the ball doesn't go out of bounds.
