The Seven Elemental Stones are the main plot device for Bomberman 64: The Second Attack. Each one of the main bosses, the Astral Knights (excluding Baelfael) carries one on them, only relinquishing it to the player upon defeat. The eighth elemental stone, the Celestial Stone, is completely different from the rest and is only an elemental by name (see below.) Every stone gives Bomberman a different ability/bomb type, starting with the standard fire bomb.
