3-D Helmet Cannon
The 3-D Helmet Cannon is an item, first appearing in Kirby: Triple Deluxe which, while worn, allows Kirby or King Dedede to fire continuous shots into the background or the foreground, depending on which plane they are in.
The 3-D Helmet Cannon resembles a hard hat, though it is blue and has a cannon extruding out of it like a head lamp. On the back, a little star insignia can be seen. Though it is worn like a hat, Kirby can take it off at any time and throw it like an item. The cannon, while worn, will fire shots continuously into a different plane from the one Kirby is situated in, allowing him to strike targets, enemies, and barriers in that plane. If used for too long, the 3-D Helmet Cannon will start to grow unstable and turn red. After too long, it breaks.
- The 3-D Helmet Cannon was also planned to be included in Kirby: Planet Robobot, but was ultimately left out. It can still be summoned in the game using hacks.
