Dark Fawful Bomb
From the Super Mario Wiki
Dark Fawful Bombs are enemies that appear in Mario & Luigi: Bowser's Inside Story and the remake, Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. They are huge, purple Bob-ombs with a lit fuse and black stars on their bodies, including a large one with red eyes imprinted on their face. They are always accompanied by two Fly Guy-like Dark Fawful Guys that carry them, similar to Shroob-ombs and their Support Shroobs from Mario & Luigi: Partners in Time.
Dark Fawful Bombs make rare appearances in the taken-over Peach's Castle, only showing up in battles where at least one Naplock or Dark Trashure was present at the beginning; they will also appear alongside Dark Mechawfuls in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, but only if Dark Trashures are present as well.
Dark Fawful Guys appear with the Dark Fawful Bomb at the top of the upper screen, waiting for an opportunity to drop the bomb onto Bowser. Bowser must uses his vacuum ability to swallow the Dark Fawful Guys, allowing Mario & Luigi to battle them; however, their height means that the player must rapidly press more than usual. If Bowser does not eliminate the Dark Fawful Guys, they eventually drop the Dark Fawful Bomb on top of him and cause massive damage. Once the Dark Fawful Guys are inhaled, the Dark Fawful Bomb lands on the other enemies, creating a giant purple explosion that deals massive damage to them.
