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 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 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.
