@gamemaster It is a complicated way of doing it. You have to beat the game one time, then go into 2 player mode. As Mario, go to 1-2 and die. Then as Luigi, go to 5-2 and have a mushroom equiped. Go to the second hammer bro, lose your power up, and hit the vine block. Go to the bottom of the vine, and wait for the hammer bro. to throw a hammer on the vine. As that happens, go up it and get killed
