Spark (ghost)

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 a wall. If Luigi touches one, it explodes and he takes ten HP of damage. Eventually, the Sparks explode anyway, and if Luigi is caught in the blast radius, he takes the same amount of damage. If Luigi sucks one up into his vacuum, the ghost explodes inside the vacuum and Luigi still takes damage. Luigi can extinguish them by spraying them with Water Element. If Luigi sprays them with Fire Element, the ghosts explode on contact. However, the Ice Element has no effect on them.
