It is one of the two boat rides. Go up and examine the ball lying on deck. I was going to tell you about Zanarkand, but I guess you already figured it out. I got so lucky with the Chocobo race. I tried it a couple times and did OK, but when it cam time to try for the celestial weapons I set aside a whole night. I got really lucky and did it the first time. Whew.
If you don’t play any blitzball, but scout for players the whole time through (you will have to go through again as you will need to capture 10 of every fiend in the game) you can build up and ass-kickin team, so that when you actually get to playing you never lose. Another helpful hint: after you finish a season of league play or a tournament immediately exit blitzball and sav e your game. Then you can soft reset the game and look at what the prizes for the next tournament/season are. If you don’t get the reel or sigil you want, then soft reset again until you do.
