Ice-Spark is a Power Combo of the Ice and Spark abilities in Kirby 64: The Crystal Shards. It transforms Kirby into a pink refrigerator with red handles and two black eyes.
While in use, Kirby stays stationary until he chooses to revert or he is damaged. The attack itself is done when Kirby opens his doors and throws up to three Food items which can destroy enemies, deal damage to bosses, and restore health when consumed. The food itself doesn't last long, and is destroyed immediately unless it hits the ground.
Like the other abilities in Kirby 64, the ability does not change Kirby's physical appearance until he uses it.
