|This article is about the item in Kirby: Triple Deluxe. For other uses, see 3D (disambiguation).|
When Kirby puts on the 3D Helmet Cannon, he immediately begins rapidly shifting from foot to foot. The helmet's cannon fires automatically into the background (or foreground, if Kirby switches planes with a 3D Warp Star). The firing rate isn't as rapid as a Crackler because of the distance the cannonballs must travel. These projectiles explode on impact, defeating enemies and destroying giant metal blocks.
As the item's time runs out, the helmet flashes green and then red. Kirby's feet move faster and faster until the helmet's cannon explodes. The helmet then breaks.
The 3D Helmet Cannon is a turquoise helmet with a star logo on the back. It has a blue cannon muzzle on the front.
