In Chopper Bros., the move involves Mario hammers Luigi into the ground with File:GBA A.png. They will then automatically jump to the enemy selected, but File:GBA B.png must be pressed at the right time to make Luigi jump underneath Mario, throwing him into the air. Mario can then swing the Hammer at will by pressing File:GBA A.png repeatedly, allowing him to chop off as much enemy HP as desired until he lands.
