can u get vivi to win the festival hunt thing in linblum?

Yes, there is. You know when you see the animal chasing Vivi? Well, help him kill the animal, and then DON'T FIGHT THE ZAGHNOL! Vivi will win if you do this. Well, he should....

Easy way, fight the Zaghnol, let it kill Freya first, then let it kill Zidane. Make sure you save Vivi from the Fang though, otherwise he wont gain anymore points. If Vivi wins you get a Theatre Ship card.

is the monster that chases him in the theatre district?

Um....no, I think it's in the same district the Zaghnol is. I think it's the industrial...but I'm not sure. I haven't been in that part of the game for a long time.

It's in the business district. Wait until you have about 8 to 5 minutes left in the game, then head for the business district. Go towards the back of the screen, (remember where the gyashl pickle cart is?) and you'll see a Fang chasing Vivi around. You have to be quick to catch them.

Once you beat the Fang, what everyone else said is right. DON'T let Zid beat the Zaghnol.

yep you guys got it!!!! just lick the zagnol not fight it!!!!! lol.... i wish there was a way to get all the prizes.....i always make Zidane win, cuz i love the dialogue between him and Garnet later in the game....:D
