Spark

The Spark usually appears as a flashing ball which clings to groups of pots or blocks. It first appeared in A Link to the Past as a ball of flashing red/blue flame which could not be harmed, first appearing in the Tower of Hera and in many dungeons later on. It can be killed in Link's Awakening using the Magic Powder or Boomerang, and in the Oracle Series using the Boomerang. It should be noted that using the Boomerang on Sparks will turn them into fairies, the same effect as Magic Powder on Anti-Fairies.

In Four Swords, Sparks do not appear, but Bombarossa acts very similar, and in Four Swords Anniversary Edition Bombarossa will replace the Sparks in the Tail Cave. In Four Swords Adventures, Bubbles act very similar to Sparks.

In Phantom Hourglass, they are invincible, and are always found in groups known as Winders.
