Spark-is are electrical enemies that appear in Kirby 64: The Crystal Shards. They are first encountered in a diamond-shaped spaceship found in Rock Star that belongs to Pix. They are small, round blue balls with red eyes that protect themselves within their shells, which resemble dark blue diamonds similar to the three crystals of Pix. Spark-is attack by shooting out electric balls and can be inhaled for the Sparkability. One larger version of a Spark-i inhabits that same spaceship as a mid-boss, and some of the Spark-is even inhabit Shiver Star's main factory. Because of their resemblance to each other, Spark-is could be considered servants of Pix. When held above Kirby's head, Spark-is shoot three electric bursts out of their eye.
