Pair a Needle with a Bomb to make Kirby explode with spiky shrapnel. Use the Control Pad to position the floating explosive.”
— Description • Nintendo Power (Volume #134)
Spike Bomb is a combination ability used in Kirby 64: The Crystal Shards, made by mixing the Needle and Bomb abilities. Taking the form of a Gordo, Kirby gains temporary hovering and invincibility for a short time. As he moves, his spikes "wobble" like those of Captain Stitch. After the duration ends, upon coming into contact with enemies, or if the B button is pressed again, Kirby explodes, sending spikes in every direction. This attack method is similar to Captain Stitch's attack, which involves him launching his spikes at Kirby in a bunch.
Kirby turns into what looks like a Gordo, a common enemy in Kirby games. While in this state, Kirby can float in any direction, but not walk or jump. He is also invincible. After a short amount of time or when B is pressed again, Kirby explodes and launches his spikes away.
