Spark

Sparks are spiky ghosts that appear in the game Luigi's Mansion. A Spark resembles a red sphere with a pointy nose. They appear in groups of two, out of a door or wall. If Luigi touched one, it would explode and he would take ten HP of damage. Eventually the Sparks would explode anyway, and if Luigi was caught in the blast he would take the same amount of damage. If Luigi sucked one up into his vacuum, the ghost would explode inside the vacuum and Luigi would still take damage. Luigi could extinguish them by spraying them with Water Element. If Luigi sprayed them with Fire Element, the ghosts would explode instantly. Ice has no effect on it, obviously.
