- This article is about the minor cannons on the Halberd in Kirby's (Extra) Epic Yarn. For the primary cannon fought as a boss in Kirby Super Star and Kirby Super Star Ultra, see Combo Cannon.
Halberd cannon[conjectural title] is a large black stationary cannon obstacle that appears exclusively in the Battleship Halberd stage in the main game of Kirby's Epic Yarn and Kirby's Extra Epic Yarn, as well as in Stage 4 of Slash & Bead. It acts similarly to Shotzo, holding position while it aims its cannon at its target to fire a slow-moving but large button volley which can cause a loss of beads if collided with. Both the cannonballs and the cannon itself can be destroyed with sustained attacks, yielding a few beads in the latter case. One large cannon from the Battleship Halberd stage in particular yields the Galaxia Furniture piece when destroyed.
The Halberd cannon comes in a few different sizes, though all of them are significantly larger than Kirby or Meta Knight. This size differential also affects the size of the cannonballs it fires, but does not change its durability or the number of beads it yields.
