Book

The Ghost Books are ghostly library books only found in Creepy Castle's library which can only be accessed by Donkey Kong. When Donkey Kong triggers a switch, it opens a secret passageway. Once he gets to it, there is a path that leads to a Golden Banana, but several Ghost Books are flying through the walls blocking the path. Donkey Kong must use the Strong Kong ability to pass the flying Ghost Books. Ghost Books can not be defeated, they can only be passed by. Ghost Books can only be seen in Donkey Kong 64.

Trivia

 * If Donkey Kong is blocking the path of a Ghost Book, it'll just glare at him and disappear instead of fly through him despite the fact that they can fly through a solid wall.
 * The attack pattern of Ghost Books is similar to the Bookends of Super Mario 64.
 * The Ghost Books look almost exactly like the Banjo-Kazooie character, Cheato.
