Ok...I'm embarassed to have to ask about this one too. I've gotten Auron's, Yuna's, and Rikku's..and know how to get Tidus's ,Lulu's, and Wakka's...least I think i know about Wakka's..though I've gotten all his overdrives I still haven't gotten his final weapon piece to come up as a reward.... I thought I knew how to get Kimarrii's, but I'm having trouble. I've successfully completed the butterfly game and got a sphere..not sure which. I did this once early in the game, then again just a few days ago while trying to complete Kimarii's weapon. Now, when I finish it, all I get is an open chest. I read somewhere that there are two different butterfly games, are they in different places with the wood? If someone knows what I'm doing wrong please help me out...with Kimarii or with Wakka...or both. Sorry to be asking this, but none of the walkthroughs I've found give much detail. Thanks.
