The Mom Bomb begins the battle looking like a normal bomb until it takes about 1,500 damage, when it then transforms into a large cloud of flame (as pictured in the table). Once this happens, she is preparing to explode and a countdown will start. After exploding, Mom Bomb transforms into three Gray Bombs and three Bombs. Bombs will explode after they have been damaged. In some versions of the game, Mom Bomb is susceptible to the Second form glitch.
