Once a giant boss is about to be defeated, Prince Dreambert will come out and tell Dreamy Luigi and Mario that the boss is in condition to be finished off. With the Finishing Bros., Dreamy Luigi jumps up high and grabs a large star. Mario then gets on the star and Dreamy Luigi tosses it down toward the weakened boss. The player must then use the Nintendo 3DS' gyroscope function to piolet Mario into the boss completely finishing it off.
