After Tidus' little performance head up to the next dock to meet the Maesters. After this you'll be taken directly to the locker room.

Here you'll get a Blitzball tutorial. After that Yuna wil come and get you. Once outside the hallway go left to the other locker room hallway. Beyhind the two closest players you'll find Al Bhed Primer VI. At the back of the hallway open the treasure chest for 2 Hi-Potions.

After this head back outside and exit the screen to the right. YOu'll be at dock 5. Go to the end of the dock and open the chests to find a Magic Sphere and an HP Sphere. Now head left through three more screens until you reach Dock 1. O'aka's here and he has items to sell. Also, on the dock you'll find chests with 600 gil and a Tidal Spear.

Now exit at the bottom of the screen and you'll be back where you started. Go south from here. You'll stumble upon Yuna. Now go north until you reach the theatre. Here you'll find a sphere moniter that will teach you how to fight fiends. YOu can also purchase movie and music spheres if you've accumulated a lot of gil. When you're done go back to where you found Yuna and go right.

This is where you'll find all the town's shops. Before going into the cafe head up the stairs on the right. At the top of the stairs you'll find a chest with 1000 gil. Then go left and talk to Luzzu and Gatta. Now go back down and take the north exit to the cafe.

After the game starts you'll need to rescue Yuna. Dock 5 is blocked off right now so you'll need to go all the way from Dock 1 fighting machina along the way.

Once you get to Dock 4 move onto the dock.

Right away have Tidus cast Haste on Lulu. Then she should cast Thunder on the crane to the right every round until it starts up and rips off half the boss. This immobilizes the boss and reduces its HP greatly. Then use Thunder and physical attacks to finish it off.

After the battle stop by the theatre. In the lobby you'll find Al Bhed Primer Vol. VII. Then head to the locker room. You'll have one more chance to review the rules. When you're ready to play Blitzball talk to Wakka. If you don't win remember you can always reset. If you don't win you won't be able to recruit higher level players for future games. Also you get a strength sphere for winning. For more help on Blitzball refer to the Blitzball Sidequest section.

After the game fiends enter the sphere pool. Have Tidus and Wakka take them down. Then you'll get a cinema of Auron. You'll have to fight a Vouivre using him. Tidus and Wakka will join him and you'll battle a Garuda. Then Seymour will summon his aeon - Anima, who finishes off the fiends

Once you get control of Tidus again follow Auron up to where you talked with Luzzu and Gatta earlier. Then talk to Yuna.
