Enemies with cutter power, Fishbones remain in one location, firing either to the left or to the right, depending on where Kirby is located. You can tell they're about to fire when the red triangle gets larger and shakes. Dodge the shot and inhale the Fishbone before it can reload.”
Fishbone is, just like his name suggests, a skeletal fish-like enemy from Kirby 64: The Crystal Shards. They are made up of three triangular body pieces and they can fire their head towards only Kirby. The pieces come in different colors: the colors are yellow in the back, orange in the middle, and red as the head which has a spot for an eye. They also start from the back and grow a lot larger. After a while they grow a brand new head. They give the Cutterability when swallowed. A giant Fishbone is a mini-boss found in Stage 3 of Rock Star. If Kirby holds a Fishbone above his head, it will fire its head at enemies. Fishbone is also one of the things fired by Acro.
Coincidentally, an enemy from the Super Mario universe has the same name, but a completely different attack strategy.
