Hey Sharpkrak,
The Ghost penguin is an interesting one due to the various abilities it has, so it's therefore quite hard to advise on how to find it. Ordinarily, I'd advise that you look up the spawn locations, see where we have last trapped a penguin and then talk to Chuck in Ardounge, who can tell you where penguins are. From that, you could use a process of elimination to determine which of his hints are for the Ghost.
However, that still doesn't account for the potentially vast roamings of the penguin or the fact that the penguins have been reset due to the system update. With that in mind, we'd recommend that you camp at the Death Plateau (past the Thrower Trolls) and hop worlds until you hit lucky. We recommend this location as it's confined and relatively easy to spot the penguin if he spawns. The penguin does make a sound effect, so it's recommended to turn your ambient sound effects on.
Hope that helps?
