The Polterghost is basically a regular ghost, but it is green in color and has the ability to possess Maximo's body. It only takes a single hit to kill it, but if it manges to touch you, Maximo will go stiff, hold his arms up, and will walk slowly, while making a few grunt noises. You have some control over him, but you cannot jump, attack, or block at all, which can put you in a bad situation in your dealing with a group of enemies. Eventually, Maximo will snap out of this possession, and you will have full control over him. The Polterghost is first seen in The Great Dank and later in Castle Maximo. These ghosts aren't really much to worry about unless your surrounded. All it takes to kill these ghosts is a well timed swing.
