Yeah, Piccolo SSB supposidly has it, but don't even bother. He says he is in contact with Kirby almost daily. But I believeh e is lieing. He keeps asking you to do stuff (Like host sevret levels, levels, and other things)
and he says "If you host ____ I'll tell you how to contact him" then you host it, and he says "If you host ____ I'll tell you how to contact him" then you host it, and he says "If you host ____ I'll tell you how to contact him" then you host it, and he says "If you host ____ I'll tell you how to contact him" then you host it, and he says.... etc.
So I say just don't bother, KirbygSSB rarely plays JJ2 anymore and says that he won't use JCS again...
