Electric exploder

An electric exploder is a stage feature in the shape of a bomb labelled with a lightning bolt icon from Dr. Mario World. When a color capsule matches the color of an electric exploder or that it is eliminated, three electric shocks will be sent out to nearby objects to be eliminated. Viruses and other electric exploders are prioritized, followed by other stage objects, with stray capsules being of the lowest priority. Even if the viruses or other electric exploders are covered inside objects such as Brick Blocks, they will still be targeted. These only appear in stage mode.
