Yea, a lot of times this forum is just posts telling people to go to GameFAQs, lol. Although when someone asks for some help on beating a boss, usually I try to give them a strategy that I used or something. I guess it depends on how much creativity people are willing to put in their answers. I haven't played all the way through Bomberman Jetters yet (the VAs kill me...) so I can't give you a detailed answer.
Oh, I've found it. It was in Area 2-1, on the top of a fountain. You had to use Pommy (LV.3) to jump to the top, then use Sharkun and destroy the vase. The Blue Hige-Hige card was inside. Thanks.
