Upon using the attack, Mario and Luigi will run into the foreground, and the Dropchopper will begin floating in mid-air near the Bros. as they run towards the group of enemies. Tilting the 3DS will make the chopper move in the direction the handheld is tilted in. Once the Dropchopper is above one of the bros, the player must press or , depending on which bro the chopper is above. Once Mario and Luigi have both grabbed onto the Dropchopper, it will slowly rise into the air. The player can continue to tilt the 3DS to change the target area below. Once the Dropchopper hovers above an enemy, either or must be pressed to cause the Dropchopper to drill down into whatever is currently below it with tremendous force, heavily damaging the enemy it directly hits and moderately damaging enemies in the target circle with the impact's shockwave. The attack will fail if both Mario and Luigi cannot grab onto the chopper in time, and if a single Bro manages to grab on, the attack continues as normal but deals minimal damage.
