These 3 FitKirbyMetaknight.pac files have a pink tornado effect to match Galacta Knight's effect files. I'm not sure if this file has differences depending on the region, but I'm assuming it does. So to be safe, you can use whichever one's name matches your game region. Just rename it to FitKirbyMetaknight.pac, and have fun.

NTSC-U = America
NTSC-J = Japan
PAL = Europe, etc.
