Robomb

A Robomb, or Strobomb, is an object found in Luigi's Mansion: Dark Moon and Luigi's Mansion Arcade. First encountered in the Old Clockworks, Robombs activate when Luigi uses the Strobulb on them. Upon activation, they pursue Luigi and then explode, causing 20 HP of damage to Luigi if he is hit. The explosion can also stun any ghosts caught in it. Some Robombs malfunction; this is indicated by a different startup sound, red electric sparks around them, and the way they behave. Malfunctioning Robombs first run into place, then charge into Luigi. Greenies use these objects to hide from the Strobulb flashes. Luigi can also find an occasional Gold Robomb. Gold Robombs act just as malfunctioning bombs, except they run much quicker and explode in contact with furniture. They release 25 bills or five Gold Bars when they are destroyed. In the ScareScraper, they are occasionally released from inspecting furniture or using the Dark-Light Device on paintings. Gold Robombs also appear as items in Luigi's Mansion Arcade, where they are referred to as Strobombs. Each player gets three to use at the beginning of each level, and they can be used to stun all ghosts onscreen.
