From WiKirby, your independent source of Kirby knowledge.
Ghost Book is a hostile flying book possessed by an unseen force which can be found in a single area of Wild World - Stage 3 in Kirby: Triple Deluxe. It is presumed to provide no Copy Ability, but it only appears in an area where Kirby has the Hypernova ability.
Ghost Book resembles an old tome with a brown leather cover. When moving, it flaps like a bird and pages fall out of it with no real consequence. When Kirby approaches, Ghost Book will close in on him and try to hurt him by collision. Ghost Book is easily defeated using Hypernova, but it can also be defeated by more modest means, such as an Air Bullet or Slide.
