Normaly theres one way to get ghost kirby and thats collecting the pieces of the ghost medal, and then going to each area, going to the level with the ghost boss ( totally random but once found stay at that level) and killing him. Then you'd suck him up.
One way that is a heck of a lot easier is to get ghost medal and then get all pieces of the secret map. BOOM. Youv got bubbled powerups resiest the urge to grap some and keep walking till you see a little ghost powerup, there you have it ghost kirby. ( NOTE: may also work without ghost medal but hasnt been tested)
