From WiKirby, your independent source of Kirby knowledge.
Ghost Dish is a hostile flying plate 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 Dish is a hovering dinner plate with noticeable wear and tear, featuring cracks and chips on its surface. It spins around in place in the air, similar to a U.F.O. in popular culture. When Kirby approaches, Ghost Dish will close in on him and try to hurt him by collision. Ghost Dish is easily defeated using Hypernova, but it can also be defeated by more modest means, such as an Air Bullet or Slide.
