Dark Fawful Bombs are a subspecies of Bob-omb and a Fawfulized enemy in Mario & Luigi: Bowser's Inside Story. Bowser can inhale the Dark Fawful Guys that hold it, causing the Dark Fawful Bomb to fall and explode, dealing massive damage to enemies. If the player takes too long to inhale the Dark Fawful Guys as Bowser, they will drop the bomb on him.
This is the only large enemy that can fight and does not drop a Blitty.
