Ghost

The Ghost shows up only during the "Spectral Tide" admin event, under Foggy weather. It is a Special fish, and the wiki rates it a very difficult catch: its movement on the bar is erratic, and landing it carries a -90% progress speed penalty. The game quote calls it a spectral entity, often a deceased person's spirit, lingering in the physical world.

Visually it is a translucent being with two round black eyes, and the wiki warns not to confuse it with the Ghoul, from the same event. The Ghost is the smaller, plumper and lighter-colored of the two. That difference carries into the numbers: the Ghoul's penalty is -95%, five points harsher, so the friendlier-looking ghost is also the gentler fight.

It has three catch lines: "DON'T CURSE ME!", "AHHH!" and "SPOOKY!" Unlike the Ghoul, the Ghost carries no Limited tag, and its page marks it only as an Admin Event fish. Bait, weight, experience and price are not listed, so everything known is the event, the fog, the slowdown and its appearance.
