The Bomb Nozzle is an item, first appearing in Kirby's Return to Dream Land which fires repeated small cannonballs at an arc when carried.
The Nozzle itself is red with gold accents and a blue star on its base. The star changes color as the Nozzle becomes more unstable, eventually flashing red to indicate that the Nozzle will break soon.
The Bomb Nozzle can be picked up, carried, and thrown like many other items in the game. Similarly, the character holding the Nozzle can only make one jump and cannot use any attack but Slide. When thrown, the Nozzle itself can deal minor damage to enemies. The main selling point of carrying the Bomb Nozzle is that, while held, it will repeatedly and rapidly fire cannonballs in an arc in front of it, heavily damaging any enemies caught in its fire and destroying blocks, including Metal Blocks in its wake.
Effective use of the Bomb Nozzle is required to obtain certain collectibles, including several Energy Spheres.
Kirby's Return to Dream Land
The Bomb Nozzle first appears in this title, where it can be found at various points in stages. When the item appears, it cannot be reset unless the stage is restarted or Kirby is KOed. The Nozzle can be carried into other rooms, but it cannot be carried out of the stage itself.
The Bomb Nozzle also appears in the Items Challenge Stage.
Kirby: Triple Deluxe & Kirby Fighters Deluxe
The Bomb Nozzle also makes an appearance in Kirby: Triple Deluxe, specifically in the Kirby Fighters Sub-Game. It serves the same function as before, though it burns out more quickly and its arc is smaller. This item carries over to the expanded version of the game, Kirby Fighters Deluxe.
